Description

200906077 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a series radio frequency (RF) power transmission network. [Prior Art] Since the processor capacity has been expanded and the power requirements have been reduced, devices that are completely independent of the operation of the wires or power lines have been proliferating. These „无緵„ devices range from cellular phones and wireless keyboards to building sensors and active radio frequency identification (RF ID) tags. Engineers and designers of such cableless devices are constantly having to deal with the limitations of portable power supplies, primarily using batteries as key design parameters. Although the performance of processors and portable devices has been doubled every 18 to 24 months (driven by M〇ore, s law), battery technology has remained only 6% per year in terms of capacity. Growth. Even with the latest technology in power-aware design and battery technology, many devices are still not meeting the cost and maintenance requirements of applications that require large amounts of cableless devices, such as logistics and building automation. Devices requiring two-way communication today require scheduled maintenance every three to 18 months to replace or recharge the device's power source (usually a battery). A one-way device that only broadcasts its status without receiving any signals (e.g., an automated utility meter reader) has a preferred battery life that typically requires replacement within 10 years. For both device types, scheduling power maintenance costs are high and the entire system to be monitored and/or controlled by a device can be devastating. Unscheduled maintenance trips are even more costly and disruptive. Macroscopically, the relatively high cost associated with internal batteries also reduces the actual or economically viable number of devices that can be deployed. 126937.doc 200906077 The ideal solution to the power problem of a cableless device is a device or system that collects and utilizes sufficient energy from the environment. The energy utilized will then be used to power a cableless unit or add a power source. However, implementation of this ideal solution may not always be feasible due to the low energy in the environment and the location limitations that limit the ability to use a dedicated energy supply. There is a need for a system that considers these factors and provides a solution to the ideal situation and also for a more restrictive environment.

The prior invention has been focused on a parallel network for power distribution, such as U.S. Provisional Patent Application Serial No. 6/683,991 and No. 60/763,582, both of which are incorporated herein by reference. in. These inventions do not explore a series network because for many applications utilizing this technology, losses from transmission lines, series switches, directional couplers (DCs), and connectors are unacceptable U, and in certain applications, such losses can ^ Or can be minimized 'for example with a coaxial cable infrastructure - compared to: network (eg - table area)' or in-building use - new or two, low loss coaxial cable infrastructure for distribution of RF power. SUMMARY OF THE INVENTION One object of the present invention is to provide a serial frequency power network suitable for providing one frequency power to a device for powering the device. The radio frequency power network, in which the part of the system, the t-hai system charges or recharges the device or directly, ...π ρ π 峪 compares with: excellent:. As an example, a series network can be used to reduce the number of rumors and numbers. Transmission lines in a parallel-connected network are typically connected to each antenna from the RF 126937.doc 200906077 transmitter. In a series network, each antenna removes a power amount from a series connected transmission line. Another advantage of a series RF power transfer network is that the network can be easily scaled. As an example, additional antennas can be added to the network by adding additional power tapping components in the series or by adding additional power tapping components to the end of the network, thereby increasing the length of the series.

Single Input Serial Network Referring generally to Figure 1, a single dry (small) series power do not match/transmit network 1 according to the present invention includes a single RF Θ 1 耵 耵 功率 power transmitter 12a and at least - power points Connect component (PTC) 14a. The single input serial network (4) terminates with a negative (four). The PTCs 14a to c are connected in series. The power is transmitted from the RF power in a direction D. Thus, in the single-input serial network, there is a single-power direction. As explained, power travels from left to right. The connection 18 (generally referred to herein as a transmission line) in the network is made via a coaxial cable, transmission line, waveguide or other suitable component. Load (4) including but not limited to antennas, terminators, consumables, directional fitters, splitter splitters, combiners, power splitters, circulators, attenuators or any other component used as a load . The transmission line 18 or the last PTC... should be terminated using a load 16 to eliminate reflections. It should be noted that the circulator and the splitter and the combiner can also feedback the reflected power back into the connection. A PTC 14a removes power from a transmission line 18 (or other connection) and supplies the removed power to another component, such as a load 16, an antenna 2, or other transmission line 18. Preferably, the PTC 14a delivers any remaining power to the lower components of the series, such as -load 16, antenna 20a, another PTC Ub or other transmission line μ. A good cradle, a PTC 14a has three or more inputs/outputs (connectors) where the power is input, output (accepted) and/or output (passion example 126937.doc -15- 200906077 eg one The PTC 14a has an input, a first output for receiving power, and a second output for transmitting power. The pTC 14a receives power at the input. The PTC Ma divides the power into a first portion and a second portion. The first portion is "accepted" and transmitted to the first output, for example to an antenna 20a (described below). The second portion is "transmitted" and transmitted to the next component in the series, such as another PTC 14b. ,

A PTC 14a can be a certain coupler, as illustrated in Figure 1. The directional coupler can be implemented as a splitter or a combiner. Preferably, one of the PTC 14ac outputs is connected to an antenna 2 button. Each antenna 20ac radiates power to a coverage area defined by a minimum electrical and/or magnetic field strength. For example, the coverage area is defined as the area (or space) in which the electric field strength of the radiation is greater than two volts per second (2 V/m). The coverage area of the I-specific antenna 20a may or may not overlap with the coverage area from the other antennas 20b, 20c. The other outputs of each PTC 14ac can be connected to a load "and other transmission lines 18." When the PTC 14ac is used as a directional coupler, the directional handles can be combined The device is designed to tap (or remove) a specific percentage (dB) from the value of the line 18. For example, a _2 〇 slave slave as h coupler with a 1000 The watt (w) input results in an output of the termination load 16. The directional couplers in the network may all have the same coupling (eg, or may be designed to use the standard on a case-by-case basis). Therefore, r is not earlier called (for example, -3, -6, -10 dB) or non-standard coupling (for example, -3.4, -8, _9 8 dB). ” In this series, the RF work can be used for agitation. The circulator 22a or the isolator is connected to the first PTC 1 blunt 126937.doc -16.200906077 to prevent reflected power that would cause damage to the radio frequency power transmitter 12a. Figure 1 illustrates an RF power transmission The device 12a, a circulator 22a, and the respective J. are connected to three pTC 14ac of an antenna 2〇ac (implemented as directional coupling) And a single-input serial network 1 that terminates the load 16. In use, the RF power transmitter 12a supplies power to each of the PTCs 14ac in the network 10 along one (or more) transmission lines. 14 buckles the power from the line and transmits the power to the individually connected antennas 2 to buckle the load 16 and the antennas 20ac, the load 16 radiates the power to the coverage area corresponding to each antenna 20ac, load 16. When in a coverage area, the device to be charged receives the power of the radiation. The received power is used to charge or recharge the device or directly to the device. Dual Input Serial Network General Reference Diagram 2. A dual input series power distribution/transmission network 10 in accordance with the present invention includes a first RF power transmitter 12a at a first end 32 of the network 30 and a second terminal μ at the network 10 The second RF power transmitter 12b.- or a plurality of PTCs 14 are serially positioned between the first RF power transmitter 12a and the second RF power transmitter 12b. Preferably, each PTC 14 is also connected to One antenna 2 button. Each antenna 2〇ac radiates power into a coverage area. The coverage area from a given antenna may or may not overlap with coverage areas from other antennas 2〇b, 2〇c. The PTC 14ac may be a two-way interface The vehicle is combined in two directions. This allows dual power direction - the first power direction A is derived from the first _ RF 126937.doc 17 200906077 power transmitter 12a and the second power direction B is derived from the second RF power Transmitter 12b. A first circulator 22a may be coupled adjacent to the first RF power transmitter 12a to be placed between the first RF power transmitter i2a and the PTC 14a in the series in series with the PTC 14a in the series in order to prevent the first RF from being caused The power of the transmission = 15 12a of the reflected power of the damage. Similarly, a second circulator 22 can be placed between the second RF power transmitter 12b and the corresponding PTC 14b in the immediate vicinity of the series.

The first RF power transmitter 12a and the second RF power transmitter ub can be on the same frequency. Then, due to component tolerances, they actually drift at the slightly different frequencies and out of phase and out of phase, averaging to a finite value. This problem is addressed in US Patent No. 1 1/699, 148 and US Temporary Specials (4) 6q/763, 582. The title of both is the power transmission network, which is hereby incorporated by reference. It is also possible that the first RF power transmitter 12a and the second RF power transmitter (3) are designed to be on different frequencies or on separate channels. The advantage of having dual (or multiple 'described below) RF power transmitter cores, (3) one of the networks is that the network 1() distributes the loss along the transmission line 18 rather than concentrating the knowledge at one end (eg, a single Enter the serial network 1〇). Another advantage is that each of the RF power transmitters 12a, 12b requires less power. For example, '- a single transmitter (1) can input 1 〇〇〇 W' or two transmitters 12a, 12b can each input 5 〇 OW. In terms of power and component cost, the two $saki input! is a cheaper network. If found to be advantageous, the RF power transmission benefits 12a, 12b may have different power levels. 126937.doc -18- 200906077 FIG. 2 illustrates a first RF power transmitter Ua, a first circulator 22a, three pTCs 14 (implemented as bidirectional couplers), and a second each connected to an antenna 20a. The circulator 22b and the two-input serial network of the second RF power transmitter pupil are 1 〇. In use, the RF power transmitters 12a and 12b supply power to each of the pTcs 14 in the network 1 along one (or more) transmission lines 18. Each π. The power is tapped from the line and transmitted to the connected antenna 2 〇 ac, respectively. The antennas 20ac radiate this power to the coverage areas corresponding to the respective antennas 2 -. When in the coverage area, the device to be charged receives the power of the fortunate shot. The received power is used to charge or recharge the device or to power the device directly. Referring to Figure 3, the bi-directional coupler % may require a combiner to: combine power from each power direction a, b. - A first-input operation having a first initial power enters the two-way clutch 36 from the first-power direction A. A second input 40b having a second initial power enters the bidirectional coupler % from the second power. One of the first input taps (example) and the second input tap (eg, in the group = combined to output the combined power 42 to the antenna 22a or another passer line 18 ( Or a combination of the two.) Write I to the other two-way consumables - the input of the two-way consumables from the input of the two-way consumables has reduced the amount of tapped power and the number from the engaged dice The number of missed (insert loss) is also the same as the input of the second input from the two-way coupler 36. When changing the + direction to the combiner 36, the existing mind is equal to the first input 4_ open the double + 4 The initial power minus the tapping amount minus 126937.d〇, •19- 200906077 The face closer 3 6 internal loss class & Φ, the door-to-door power (insertion loss). 々4-> _ its ' The bidirectional coupler 36 can be designed to not sense the direction of the power, and thus is not required to be the combiner 38. Therefore, the PTC 14a (in this case, a two-way coupler) can be simply referred to as a coupler. Referring to the serial network as shown in FIG. 4 'Multiple input series power distribution/transmission according to the present invention', the road 1 includes The distributor 52 is connected by a first radio frequency power transmitter 12a, a second radio frequency power transmitter 12b, and at least a third radio frequency power transmitter n, for example, in a star or cluster pattern. One or more ?1^ 14ac Preferably, the first, second and/or third RF power transmitters 12a-c can be positioned in series with the power splitter 52. Preferably, each PTC 14 button is also connected to an antenna 20ac. The antenna 2 〇ac radiates power into a coverage area. The coverage area from a given antenna 20a may or may not be from other antennas 2〇b, 2〇(;

Overlay Area Overlap D These PTC 14acs can be bidirectional couplers that couple waves in both directions. The power splitter 52 couples waves (or routing power) in multiple directions. This allows a plurality of power directions - a first power direction A is derived from the first RF power transmitter 12a, a second power direction b is derived from the second RF power transmitter 12b, and a second power direction c is derived from the third RF power transmitter He. The power splitter 52 can be a combiner or a splitter. In contrast to the dual input serial network 10 (illustrated in FIG. 2), in a multiple input serial network, the network 10 includes not only one of the first inputs 40a from the first RF power transmitter 12 & The second input 126937.doc • 20· 200906077 of the second RF power transmitter i2b further includes at least one third input 40c from the third RF power transmitter. Referring to Figure 5, the number of _s on the power splitter 52 can be increased by using a 1 to N splitter to provide N+1 turns on the power splitter 52. Each output of the output on splitter 54a is coupled to one of the outputs of the other splitter 54b. For example, as illustrated in Figure 5, a three-part power splitter 52 includes three (1) splitters 54. The power from the direction A enters the first port 56a, and is separated by the splitter 54a and directed to the splitter servant and W. The power from direction B enters the second pass and is separated by the separator state and directed to splitters 54a and 54e. Power from direction c enters third 埠 56C and is separated by splitter 54c and directed to splitters 54a and 54b. The multiple input serial network 1 of Figure 4 may include additional RF power transmitters and/or additional power splitters connected in various configurations. In other words, the '罔路〇' can be extended such that more than one power splitter 52 is connected to the plurality of RF power transmitters 12ac. Thus, the network 10 can include multiple star graphics or clusters. 4 illustrates a multi-input serial network 1B having a first RF power transmitter 12a, a second RF power transmitter 12b, a third RF power transmitter 12c, and a power divider 52. A first pTC 14a (implemented as a bidirectional coupling) is coupled between the first RF power transmitter 12a and the power splitter 52. A second PTC 14b is coupled between the second RF power transmitter 12b and the power splitter 52. A third pTc i4c is coupled between the third RF power transmitter 12c and the power splitter 52. Each pTc 14ac is also connected to an antenna 2〇a. 126937.doc -21 - 200906077 In use, the RF power transmitters 1 23 to C along the transmission line 8 supply power to the PTCs 14 in the network 10. Each PTC 14ac taps power from the line and transmits the power to the connected antenna 2 respectively. The antennas 20ac radiate this power to the coverage area corresponding to each antenna 2 snap. When in a coverage area, the device to be charged receives the power of the radiation. The received power is used to charge or recharge the device or to power the device directly.

Adjustable PTC In general, the amount of power leaving the PTC 14a is equal to the amount of power entering the pTc 14a minus the amount of power tapped by the pTC Ha. Thus, the initial amount of power from an RF power transmitter (3) is reduced each time it passes through the -PTC 14ac. For example, a network sentence, including him and secret *. Λ t .

126937.doc 3 to make the bidirectional coupler screw or electric controller) to change the distance or electrical characteristics. The coupling factor depends on the distance d between the main line 62 and the primary line 64 of the two-way number or the electrical characteristics of the coupler. It should be noted that changing the length of the face closer also changes the characteristics. By including a field adjustable pTC6 in the network 10, the power of the entire network (4) to the antennas can be maintained at a "substantially constant level."

Referring to Figures 7 and 8, multiple paths can be presented in a network. For example, referring to Figure 7, network 10 includes a series connection of a first pTC 14a (implemented as a directional distraction) and a power splitter 54 (1 to 2) - RF power transmission, 12 a. One of the power splitters 54 is connected to the second output 14b and terminates with a stop-termination antenna (load) 16b. The second output of the power splitter 连接 is connected to the first: PTC Me in series with a fourth PTC 14d and terminated by a second terminating antenna (load) 16d. Each of the first, second, third, and fourth PTCs 1A to 4 is connected to an antenna (first antenna 2a, second antenna 2b, third antenna 2c, and The fourth antenna 20d) couples power to the individual antennas 2〇&amp; to d to radiate power into the various coverage areas. When in a coverage area, the device to be charged receives the power of the radiation. The received power is used to charge or recharge the device or to power the device directly. For another example, referring to Fig. 8, a network 1A includes a radio frequency power transmitter 12a connected in series with a circulator 22 connected to a first PTC 14a (implemented as a directional coupler). The first ρτχ 1牦 is connected in series to a second PTC 14b and a third PTC 14c and terminates with a first terminating antenna (load) 16c.
