It is understood that the detailed description and specific examples of the invention are intended to be illustrative of the embodiments of the invention, and are not intended to limit the scope of the invention. [Embodiment] The following description has only exemplary characteristics and does not have any meaning limiting the present invention, application, or use. 1 to 4 are exemplary antenna assemblies that embody one or more aspects of the present invention. As shown! The 'antenna assembly 1' shown therein generally comprises: a tapered loop antenna element 1〇4 (also shown in 囷5 to ι〇), a reflector TL 108; a balanced/unbalanced converter 112, And a housing 116 having a removable end piece or portion 12". ❹ As shown in FIG. 11, the antenna component 1 can be used to receive digital television signals (a subset of high definition television (HDTV) signals) and transmit the received signals to an external device. For example, TV. In the embodiment shown in the figures, a coaxial cable 124 (Figs. 2 and n) is used to transmit the signal received by the antenna assembly 100 to the television (Fig. u). The antenna assembly (10) can also be positioned on other generally horizontal surfaces such as a dining table, a coffee table, a desk table, a scaffold, etc. Alternatively, other embodiments may also include antenna assemblies that are positioned elsewhere and/or supported using other components. 1 200926506 In one example, the antenna assembly 100 may include a 75 ohm RG6 coaxial cable 1 24 that is coupled to an F-type connector (although other suitable communication links may be utilized. Other embodiments may also be used. Include other coaxial cables or other suitable communication links. As shown in Figures 3, 5, and 6, the tapered loop antenna element 1 〇 4 has a generally annular shape that is surrounded by an outer circumference or outer The peripheral portion MO and an inner peripheral or inner peripheral portion 144 are cooperatively defined. The outer peripheral or outer peripheral portion 140 is generally circular. The inner peripheral or inner peripheral portion 144 is also generally circular, such that the tapered The loop antenna element 丨〇 4 has a generally circular opening 148. In a particular embodiment, the tapered loop antenna element has an outer diameter of about two hundred and twenty millimeters and an inner diameter of about eighty millimeters. The example includes the inner diameter being offset from the outer diameter ' such that the middle of the circle (the midpoint of the inner shuttle) substantially defined by the inner diameter portion 144 is substantially deviated from the outer diameter portion 14 Center of the circle (in the outer diameter ) about twenty millimeters below. For φ, the inner diameter of the inner diameter can be offset from the outer diameter, so that the midpoint of the inner diameter is located about twenty millimeters below the midpoint of the outer diameter. Deviation of the diameter of the tapered loop antenna element 1〇4 provides a taper such that at least one of the top end portions 126 (shown in Figures 3, 5, and 6) is wider than the other P-knife (Fig. 3, 5, and the end portion 128 shown in Fig. 6. It has been found that the tapered structure of the β-thinned loop antenna element 1() 4 improves the performance and aesthetics. As shown in Figures !, 3, 5, and 6, The tapered loop antenna element 1〇4 includes 3 2 symmetrical first and second halves or curved portions 15〇, 152, such that the first and second halves or curved portions 15 are passed to the second half Or a curved image of the curved portion 200926506 152. Each "curved portion", generally extending at the corresponding end portion 12..., and tapered or gradually increasing until the middle or top portion of the tapered loop antenna element # 126. The tapered loop antenna element #1〇4 can be positioned in the alignment with the housing u6, so that the tapered circuit The wider portion 126 of the line element 1 〇 4 is at the top end and the narrower end portion 128 is at the bottom. Continuing to refer to Figures 3, 5, and 6' the tapered loop antenna element 1 〇 4 includes a plurality of spaced end portions | 128 In a particular embodiment, the separation ends of the tapered loop antennas το# 104 are separated by a distance of about 2 $

Millimeter. The t-generation embodiment may comprise an antenna element having a separation distance greater than or less than 2.5 mm. For example, a particular embodiment includes an antenna element having a distal end portion spaced apart by a distance of between about 2 mm and about 5 mm. The spaced apart end portions may define an opening therebetween that is operable to provide a gap feed line for use with a balanced transmission line. The end portions 128 include a plurality of fastening holes 132 in a pattern corresponding to the fastening holes 136 of the PCB balance/non-balance converter n2. Accordingly, mechanical fasteners (for example, 'screws, etc.) can be inserted into the fastening holes after the fastening holes 132, 136 are aligned for attaching the PCb balance/unbalance converter 112 Connect to the tapered loop antenna element 1 〇4. Alternative embodiments may have differently configured fastening holes (e.g., 'a greater number or a smaller number of owners, different shapes, different sizes, different positions, ..., etc.). Still other embodiments may include other attachment methods (e.g., soldering, .., etc.). As shown in Figures 4 and 7 through 10, the tapered loop antenna 200926506 shown in the Figure is substantially in the exemplary embodiment having a substantially constant or constant thickness, such as the ten sides of the sequence. The thickness of the tapered loop antenna element 104 is & 4 Real (4) may include - thicker or thinner antenna elements ^ δ 儿 'Specific embodiment can be exemplified by a thickness of about 35 microns (lifting copper, bismuth, no station, J ^ ^ 5 1 〇ζ :etc.) Antennas... wherein the antenna elements are mounted on a printed circuit board. Further embodiments may include a self-contained, self-supporting antenna element made of a factory copper, etc., 'having a thickness of about .5 mm to about, in the example, 兮, one by one ^ ^ antenna 7L pieces Included in a very thin package system surrounded by a support plastic enclosure for reducing the associated material, alternative embodiments may include a manner different from the tapered loop antenna component 104 shown in the figures. Configured antenna elements. For example, other embodiments may include a non-fade loop antenna element 2 having a centered (no offset) opening. Additional embodiments may include a loop antenna element defining a free end portion 128 that is substantially circular or Q-ring without separation. Further embodiments may include a peripheral/outer peripheral portion, an inner peripheral/inner peripheral portion having a different size or a different shape (e.g., a non-circular shape, for example, an oval, a triangle, a rectangle, etc.), And/or an open antenna element. The antenna element 104 (or any portion thereof) can also be configured in a variety of configurations (eg, shape, size, etc.) based at least in part on the intended end use and the signal to be received by the antenna assembly. And set. Various materials are available for the antenna element 104. For example, the tapered loop antenna element 104 may be constructed of a metal electrical conductor, for example, 200926506, copper, non-recorded steel, or other alloys, etc. In another embodiment, the tapered loop antenna element 104 may be stamped from sheet metal or may be produced by selectively etching a copper layer on a printed circuit board substrate. Figures 1, 3, and 4 show an exemplary reflector 108 that can be used with an antenna assembly. As shown in Figure 3, the reflector 1A 8 includes a substantially flat or planar surface 16". The reflector 1 〇 8 also includes a baffle, lip, or sidewall portion 164 that extends outwardly relative to the surface 16G. The reflector 108 is generally operable to reflect electromagnetic waves substantially toward the 3H tapered loop antenna element 1 〇 4 . The size of the reflector and the spacing from the antenna element have been noted by the inventors of the present invention. The size of the reflector and the spacing from the 5G piece of the 5G antenna can seriously affect performance. Placing the antenna element too close to the reflector provides an antenna with good gain 'but' which results in a narrow impedance bandwidth and poor VSWR (voltage Q standing wave ratio). The size is small, but these designs are not suitable for the intended broadband application. If the antenna element is placed too far away from the reflector, the gain will decrease due to an incorrect phase relationship. When the size and proportion of the antenna element, the size of the reflector, the size of the baffle, and the spacing between the antenna element and the reflector are properly selected, there is an optimum configuration that utilizes the small reflector element of the electrical Near zero coupling produces an enhanced impedance bandwidth' while mitigating the phase cancellation effect. The net result is an exemplary balanced result between impedance bandwidth, directivity or gain, radiation efficiency, and physical size. 200926506 In the embodiment shown in this figure, the reflection @(10) is generally a square having four surrounding sidewall portions 164. Alternative embodiments may include a reflector having a different configuration (e.g., different shapes, sizes, fewer side soil knives, ..., etc.). The side walls can even be reversed to point to the opposite side of the antenna element. The contribution of the sidewalls slightly increases the electrical dimensions of the reflector and improves the impedance bandwidth. In one dimension, the reflector 108 of one of the exemplary embodiments has a generally square surface 160 having a length and width of about 228 mm. Continuing/Ίexample' The reflector 1G8 can also have a plurality of peripheral sidewalls. The height of each of the peripheral sidewall portions relative to the surface 丨6〇 is about 25.4 mm. The dimensions provided in this figure (as all dimensions presented herein) are merely examples for purposes of explanation. For example, any of the antenna components disclosed herein may be adapted to a particular application and/or the antenna. The signals to be received or transmitted by the component are configured into different dimensions. By way of example, another embodiment may include a reflector 108 having a baffle having a height of about ten millimeters, a lip, or a surrounding sidewall portion 164. The shoulder plate, lip of another embodiment may be in the opposite direction of the antenna element. In this embodiment, it may also add a top cover to the open box to accommodate a receiver circuit board or other electronic component shielding package. With further reference to FIG. 3', a slit, opening, or recess 168 may be provided in the surrounding sidewall portion 164 of the reflector to assist in positioning and/or attaching the reflector 108 within the housing 116. The outer casing end device 120 is in an exemplary embodiment in which the reflector 1A can be slidably positioned within the outer casing 116 (Fig. 1). The fastening holes 172 of the housing end pieces 120 200926506 can be aligned with the opening i68 of the reflector so that the fasteners can be inserted into the aligned openings 168, 172. Alternative embodiments may have reflectors without such openings, slits, or notches. 1, 3, and 4 illustrate an exemplary balanced/unbalanced converter 112 that can be used in conjunction with the antenna assembly 100 to convert a balanced line to an unbalanced line. In the embodiment shown in the figures, the antenna assembly 〇 includes a printed circuit board having the balun 112. The PCB having the balun Π 2 is affixed to the tapered loop antenna element 1 〇 4 (Fig. 3) through fasteners and fastening holes 32 1 32 and 136. Alternate embodiments may include different components for connecting the balun 丨 12 to the tapered loop antenna elements and/or different types of balanced/unbalanced converters 112 including the printed circuit board transformer. As shown in FIG. 1, the housing 116 includes a plurality of end devices 12A and a middle portion 180. In this particular example, the end pieces 120 are removably attached to the intermediate portion 180 by mechanical fasteners, fastening holes 172, ι 74, and threaded slots 0 176. Alternative embodiments may include an outer casing having an integrally formed, stationary end piece. A preferred embodiment can include a housing having one or more removable end devices, such as snap-fit, friction flt, or interference matching. Interference fits the middle portion of the housing without the need for mechanical fasteners. As shown in Figure 2, the outer casing 116 is generally U-shaped with two spaced apart P-knifes or components i 84 that are connected by a generally flattened jaw or portion 186. . In this embodiment, the components 12 200926506 184, 186 cooperatively define a generally u-shaped profile of the outer casing 116. As shown in FIG. 1, the tapered loop antenna element 1A4 can be positioned in an upright member 184 that is different from the upright member 184 in which the reflector 108 is positioned. In a particular example, the housing 116 is configured to be positioned (eg, shaped, dimensioned, etc.) in the tapered loop antenna element 104 and the reflector log in the housing IK The individual tapered loop antenna elements i 〇 4 are spaced apart from the reflector i by about U4·4 mm. In addition, the outer casing 6 can also be configured such that the side portions 184 of the outer casing are generally square with a length and width of about 25 4 cm. Accordingly, the antenna assembly 1 can thus have a very small total footprint. The shapes and dimensions are for illustrative purposes only. For example, the particular configuration of the housing (e.g., shape, size, etc.) may vary depending on the particular application. The 5H outer casing 116 can be constructed of various materials. In a particular embodiment, the outer casing 116 is constructed of plastic. In embodiments where the antenna assembly is intended to function as an outdoor antenna, the housing may be constructed of materials that are resistant to weather, for example, water and/or UV resistant materials, etc. In addition, the outer casing 116 (or its bottom portion) may also be constructed of a material that will have a very high coefficient of friction on the bottom surface of the outer casing 116. This will thus assist in preventing the antenna assembly 100 from slipping relative to the surface supporting the antenna assembly 1 (e.g., the top surface of the television as shown in Fig. 11, etc.). In a particular embodiment, the antenna assembly can also include a digital tuner/converter (ATSC receiver) built into or within the housing. In some exemplary embodiments of the present invention, the digital tuner/converter is operative to convert the digital signal received by the antenna assembly into an analog signal. In an exemplary embodiment, a reflector having a reverse baffle and a cover plate can serve as a shielding enclosure for the ATSC receiver. The shaded box reduces the effects of the radiated or received interference on the tuner circuitry. Placing the tuner in this enclosure saves space and eliminates (or reduces) the coupling between the antenna element and the tuner, which would otherwise have a negative impact on antenna impedance bandwidth and directivity. In various embodiments, the antenna assembly 100 is tuned (and optimized in a particular embodiment) for receiving signals having frequencies associated with high definition television (HDTV), the frequency range of which is About 47 〇 million Hz and about 690 megahertz. In these embodiments, narrowly tuning the antenna assembly 100 for receiving the HDTV signals allows the antenna elements to be fully functional but still function adequately. Because of its small discrete physical size relationship, the overall size of the antenna assembly 1 can be reduced to provide a smaller footprint of the antenna assembly 100, for example, when the antenna assembly 100 is used. It may be very advantageous to be indoors and placed on top of the TV (for example, Figure 11 ··· etc.). Exemplary operational parameters of antenna assembly 100 will now be provided for illustrative purposes. For example, the operational parameters may be varied in other embodiments depending on the particular application and the signals to be received by the antenna assembly. In a particular embodiment, the antenna assembly 1 can be configured to have operational parameters substantially as shown in FIG. 12, shown in the figure as an antenna assembly 100 having a seventy-five ohm unbalanced coaxial feed line. An exemplary embodiment 200926506 computer-simulated gain/directivity and a plot of S11 versus frequency (in millions of hertz). In other embodiments, a 3 ohm ohm balance twin lead can be used. Figure 12 generally shows the antenna assembly! The 具有 has a fairly flat gain curve from about 698 MHz. Furthermore, Figure 12 also shows that the antenna assembly 100 has a maximum gain of about 8 dBi (decibel value based on the isotropic gain) and has an output having an impedance of about 75 ohms. Further, Fig. 12 also shows that S 11 is below -6 dB in a frequency band from about 47 〇] vlHz to about 698 MHz. The value of s 以下 below this value ensures that the antenna has a good match and operates with very high efficiency. In addition, an antenna assembly can also be configured to have very good forgiving aiming. In these exemplary embodiments, the antenna assembly does not need to be re-targeted or reoriented each time the television channel is changed. 0 shows another embodiment 200 of an antenna assembly embodying one or more aspects of the present invention. In the embodiment shown in the figures, the antenna assembly 200 includes two substantially side-by-side tapered loop antenna elements 204A and 204B (shown in Figure 13) having a generally figure-eight configuration. The antenna assembly 200 also includes a reflector 208 and a printed circuit board balance/unbalanced converter 212. The antenna assembly 200 can be provided with a housing that is identical or different from the housing 116. In addition to having two tapered loop antenna elements 204A and 204B (and thus an improved antenna range can be achieved), the antenna assembly 200 can be similar to the antenna assembly in its at least some embodiments in its 15 200926506 manner. To operate and configure. Figure 20 is a graphical representation of the computer-simulated directivity of antenna assembly 200 and s丨丨 versus frequency (in millions of hertz) of antenna assembly 2000 in accordance with an exemplary embodiment. 14 through 19 are additional exemplary embodiments of an antenna assembly embodying one or more aspects of the present invention. For example, shown in Figures 14 and 5 is an antenna assembly 300 having a tapered loop antenna element 304 and a support base 388. In this exemplary embodiment, the antenna assembly 3 is supported on a horizontal surface 390, such as a desk or a top surface of a dining table top. The antenna assembly 300 can also include a printed circuit board balanced/unbalanced converter 3U. In a particular embodiment, an antenna assembly can include a tapered loop antenna element (for example, 304, 4〇4, 5〇4, ..., etc.) in the middle portion of the antenna element and/or the first The second curved portion has a plurality of openings (for example, holes, recesses, dimples, voids, small holes, etc.), wherein, for example, the openings can be used to help align the antenna elements to one The support base and/or the antenna element is fixed to a support base. By way of example, a plastic support structure having protrusions, bumps, or projections can be used to support a very thin metal antenna element having such openings, such protrusions, bumps, or protrusions. The outlets are aligned with the openings of the antenna element and are frictionally received within the openings of the antenna element, such that the frictional fastening or snapping helps secure the antenna element to the plastic support structure . By way of another example, Figure 16 shows an antenna assembly 4 having a tapered loop antenna element 404 and an indoor wall mount/support mount 488. In this example, the antenna assembly is placed on the wall 49〇. The antenna assembly 200926506 400 can also include a printed circuit board balun/unbalanced converter. However, the balun is not shown in Figure 16 because it will be obscured by the pedestal 488. The antenna assemblies 3A and 400 shown in Figs. 14 to 16 do not include a reflector identical to the reflectors 108 and 208. In certain embodiments, the antenna assemblies 300, 400 do not require a reflector to provide a good VSWR (voltage standing wave ratio). However, in other embodiments, the antenna assemblies 300 and 400 do include such a reflector. . The antenna assemblies 3 and 4 can be operated and configured in a manner similar to the antenna assembly and in at least some embodiments. As shown in Figures 14 through 16, the circular shapes of the support seats 388 and 488 are merely exemplary embodiments. The support seats 388 and 488 can have many shapes (for example, squares, hexagons, etc. removing a reflector may result in an antenna having a smaller gain but having a more bidirectional mode for signal strength bits. This may be very advantageous in the particular case of high and various directions. The other exemplary embodiments of the antenna assembly for housing outdoors are shown in Figures 17 to 19. The antennas shown in Figures 17 and 18 The component 5 has a tapered loop antenna element 504, a printed circuit board balun 512, and a support base 588, wherein the antenna assembly 5 is mounted outdoors to a vertical antenna or Antenna rod 592. The antenna assembly 600 shown in Fig. 19 has two tapered loop antenna elements 6〇4-8 and 6〇4B and a support base 688, wherein the antenna assembly 6 is mounted outdoors to a vertical Antenna or antenna mast 692. The antenna assemblies 500 and 600 include reflectors 5〇8 and 6〇8. And 17 200926506 reflectors 108 and 208 are substantially solid planar surfaces, with reflectors 508 and 608 having a grid Grid or The grid surfaces 560 and 660. The reflector 508 also includes two peripheral flanges 564' and the reflector 608 includes two peripheral flanges 664. A grid reflector is generally advantageous for external applications to reduce wind loads ( Wind loading). For outdoor use, the size is usually less important, so the grid reflector can be made slightly larger than the equivalent indoor model 'to compensate for the inefficiency of the grid. The larger size of the grid reflector is also The need for baffles can be eliminated or reduced, and baffles are generally more important for indoor models that tend to be about the size > relative to the limits of the performance curve. Any of the embodiments shown in Figures 14 through 19 can be One or more devices (eg, balanced/unbalanced converters, reflectors, etc.) including the same components as the antenna assembly 100. Further, any of the embodiments shown in Figures 14 through 19 can be In at least some embodiments, they operate and are configured in the same manner as antenna assembly 1. According to a particular embodiment, 'for ultra high frequency (VHF) range (for example, 17 〇, megahertz to 216 hundred) Wanhez...etc.) The antenna element of the signal may be less rounded, but still according to the basic electrical geometry of the antenna element disclosed herein. For example, a VHF antenna element can be configured to be used along the antenna element. The inner and outer circumferences provide an electrical path of more than one length. The correct combination of components having an electrically small reflector can thus be achieved in directionality as in other exemplary antenna assemblies disclosed herein. A better balance is achieved in terms of efficiency, bandwidth, and physical size. For example, an exemplary embodiment of an antenna component 7A, shown in Figures 21 through 24, can be used to receive VHF signals (for example) In other words, the signal falls within the bandwidth of 170 megahertz to 216 megahertz...etc.).

By means of complex coupling theory, in the particular embodiment, the electrical path system 19 200926506 defined by the inner and outer loops of the antenna ... 〇 4 operates at approximately 17G megahertz to approximately 216 The megahertz VHF bandwidth range is much more efficient, so the size of the antenna assembly can be reduced (for example, '75% reduction in size, etc.) and still provide satisfactory operational characteristics. The beater 793 can be configured to provide impedance matching to the antenna element 704 (eg, sized, shaped, placed, etc.), in a particular example embodiment, The tuning rod 793 can provide the antenna element 704 - more closely matched to the impedance of a 3 ohm ohm transformer. In a particular example, the end portions 728 of the antenna elements 7〇4 are separated by a distance of about 2.5 mm.

In this particular example, although the various portions (728, 794, 795, 796, 793) of the antenna element 704 are all constructed of the same aluminum tube; however, this is not required for all embodiments. Alternate embodiments may include a differently configured antenna element, such as from a different material (eg, other materials than aluminum, a portion of the antenna elements are composed of different materials, etc.), non-rectangular shapes, and/or Different dimensions (for example, separated end portions greater than or less than 2.5 mm...etc.) are formed. For example, a particular embodiment includes a 20 200926506 » antenna element having an end portion separation distance of between about 2 mm and about 5 mm.
