  • the second end is bare of conductive material.
  • An upper conductive layer 24 and a lower conductive layer 28 cover partially respectively the upper and lower sides 124 and 128.
  • the elongated body presents a sensibly rectangular section, the dimensions of the section being sensibly smaller that the total length of the body, to give the antenna an elongated form.

  • the two conductive layers are electrically separated from each other along the body 21 between the two layers.
  • the lower conductive layer is connected to a lateral conductive layer 25 covering the first end 125.
  • the upper conductive layer 24 is connected to the lateral conductive layer 25 through a conductive loop formed with two arms 26 and 26' located on the upper side.
  • An opening 27 is provided on the first end 125 to receive connections means 10 of the antenna 20 to a radio communication equipment (see FIG. 2c).
  • this connection means generally comprises a first electrically conductive path 112 and second electrically conductive path 110, electrically separated from each other.
  • the first electrically conductive path 112 is a coax cable sheath (a copper mesh) and the second electrically conductive path is a coax cable core.
  • the coax cable as seen on FIG. 1a and on FIG. 3, further comprises an inner insulation 105 and an outer insulation 115.
  • the opening 27 is adapted so that when inserting the connection means, the electrically conductive path extends further into the opening 27 than the first electrically conductive path 112.
  • the lateral conductive layer 25 extends partially into the opening 27 to electrically connect the first electrically conductive path 112 so that the latter is electrically connected to the lower conductive layer 28.
  • the second electrically conductive path extends in such a way that it is electrically connected to the upper conductive layer 24.
  • the opening opens up on the upper side 124, as seen later on.
  • a recess In the assembly of FIG. 2c and the detailed view of FIG. 2d, a recess
  • the upper conductive layer 24 extends on the walls of the recess up to the lateral conductive layer 25. In a preferred embodiment, the upper conductive layer 24 is continued to the bottom of the recess, all the way to arms 26 and 26' that extend from the bottom of the recess to the first end 125 and its lateral conductive layer 25.
  • the opening 27 extends inside the antenna body 27 till it opens up on the upper side 124, and more precisely in the recess 200, at the vicinity of the recess bottom.
  • the recess is preferably deep enough to allow the opening 27 to open between the two arms 26 and 26', i.e. above the recess bottom, as seen on FIG. 2d. In this area of the recess between the two arms 26 and 26', no conductive layer is provided on the recess wall.
  • the insulation layers of the coax cable are cleared so that the core 110 extends further than the metal sheath 112, as seen in FIG. 1a and FIG. 3.
  • the metal sheath comes into contact with the extension of the lateral conductive layer inside the opening 27, and the tip of the coax cable, i.e. the core 110 comes into contact with the upper conductive layer 24.
  • the two contact zones are separated with the inner insulation 105 partially lying against the recess wall between the two arms 26 and 26'.
  • the core 110 is welded to the conductive layer 24 at the bottom of the recess through soldering 141.
  • the inner insulation 105 is freed from its outer insulation and outer sheath so that it lies at the bottom of the recess, on a section 135 with no conductive layer.
  • the outer sheath is freed of its outer insulation so that a section 112 can be inserted inside the opening 27 to be in contact with the conductive layer covering the walls of the opening 27.
  • a soldering 142 allows to weld the sheath 112 against the conductive layer.
  • the transverse dimensions of the antenna are relatively small compared to the length of the antenna body.
  • the section of the antenna is sensibly of the same size that the section of the coax cable, therefore it does not require much more room than the cable itself.
  • Conductive layers can be incorporated on the antenna body 21 using techniques like MID (molded interconnect device). All known MID techniques may be used to manufacture the antenna, such as the Single Shot Molding with Photo Imaging, the Two Shot Molding, or the different Film Techniques. A two shot molding MID can be advantageously used to position the conductive layers on the elongated body 21 of the antenna. This technique uses two separate molding cycles and usually different polymers to form the body. It requires the construction of different mold cavities for each shot.
  • MID molded interconnect device
  • a first shot which usually contains platable catalyzed resin, is injection molded in one cavity in a mould. This produces a first-stage molding having identifiable areas for placement or incorporation of further molding material for additional processing. The first-stage molding is then inserted into a second cavity where a second shot, generally of non catalyzed resin, is introduced into the mould. This typically produces a molding with exposed, platable, catalyzed resin on its surface, the patterns of which define the required circuit tracks of the conductive layers. The areas not to be plated are covered with the second molding. As part of the plating process, the molding may undergo a chemical treatment to enhance the ability of catalyzed resin to accept plating. The molding is finally metal plated, for example copper plated, to a specified thickness.
  • Metallic or organic finishes may then be applied.
  • a variation of this technique is to use resins which do not contain a plating catalyst.
  • the first shot is molded and chemically treated with a catalyst to render the polymer metal sensitive before molding the second shot.
  • Copper plating is then undertaken and only the resin that has been chemically treated plates to form circuits. In both instances, only the polymer which is sensitive to the metallization will keep the metal after the plating.
  • the antenna body 21 is made of two different moldings 130 and 135.
  • the molding 130 carrying the conductive layers, is made of the polymer sensitive to plating, while the molding 135 is not. All the conductive layers, as presented in FIGS. 2a to 2d, and 3, i.e. the upper layer 24, the lower layer 28, the lateral 25, the arms 26 and 26', as well as the layer extending within the opening 27, actually define the outline of the molding 130 of metal sensitive polymer.
  • the regions of the antenna body 21 which are not covered by the conductive layers or plating belong to the second shot of molding.
  • the second molding covers the first molding to define the free areas on the first molding to be covered during the subsequent plating operation with the conductive layers.
  • the second molding which remains metal free after the plating operation, allows to define the outline of the conductive layers defining the antenna as it prevents some areas of the first molding to be plated during the plating process.
  • the antenna defined here before displays a generally rectangular section.
  • Another embodiment, presenting a generally round section is show in FIG. 4.
  • the same numbers refer to the same parts.
  • the antenna of FIG. 4 displays the exact same characteristics of the first embodiment, except for the round section.
  • the body 21 presents a cylindrical form, which comprises an upper half cylinder 124 and a lower half cylinder 128.
  • the upper half cylinder carries the upper conductive layer 24, and the lower half cylinder carries the lower conductive layer 28.
  • An opening 27 is also provided on the first end 125 covered with the lateral conductive layer 25.
  • the coax cable 21 is cleared of its external layers so that its core 100 can extend to the bottom of the recess when the cable 10 is inserted inside the opening 27, and be welded to the layer 24.
  • the outer conductive sheath (not shown) of the coax cable 10 is inserted into the opening 27 so that it can be welded to the layer covering the walls of the opening.
  • the conductive layer 24 is connected to the lateral conductive layer 25 through the arms 26 and 26', which form a loop through which the opening 27 opens on to.
  • Other connection means could be used such as only one arm, or a different pattern of conductive layer, as long as the core 110 of the coax cable 10 can be welded to the conductive layer 24.
  • the antenna assembly according to the invention offers a small transversal section, of dimensions sensibly equivalent to the section of the coax cable. Thus the antenna does not need more room than the cable itself. Thus the integration of the antenna is facilitated, specifically for computer flat panel displays.
