    • A planar reconfigurable antenna that is capable of generating omnidirectional and directional radiation patterns over a wide frequency band or over multiple frequency bands includes a substrate, one or more pairs of conductive elements on at least one side of the substrate, a common RF feed point, and respective switches that selectively connects one or all of the conductive elements to the common RF feed point. An omni-directional radiation pattern is generated when all of the conductive elements are connected to the common RF feed point, while a directional radiation pattern is generated when only a pair of conductive elements on opposite sides of the substrate are connected to the common RF feed point. In the directional radiation mode, the conductive elements that are not connected to the common RF feed point act as a reflector for other conductive elements that are connected to the common RF feed point.

    • An antenna 10 comprises at least a first pair 12 of elongate radiating elements and a second pair 14 of elongate radiating elements. Each pair comprises a first element 12.1 and a second element 12.2. Each element has a feed end 12.11 and a distal end 12.12. The first and second elements of each of the at least first pair and second pair have their respective feed ends 12.1 1, 12.21 in juxtaposition relative to one another and extend in diverging relationship relative to one another in a direction from their feed ends towards their distal ends. The at least first and second pairs are electrically connected in parallel. In some embodiments the elements may diverge exponentially. The invention also relates to antennas which may be packaged in at least partially knock-down form to be assembled or deployed conveniently at a user site.

    • The present invention relates to an antenna which is used in mobile digital broadcast receiving devices, and which enhances signal receiving performance of the receiving device by enabling signal gain in three dimensions, and which comprises an elastic substrate (2) having conductive trace (4) disposed in the middle of the substrate, conductive micro-strip paths (5) extending from the trace (4) in opposed directions towards the left and right ends of the substrate and the ends of which are furcated into parallel branches (6) of different lengths extending perpendicular to the conductive paths (5) towards the bottom end of the substrate. The substrate (2) comprises portrusions (3) at the bottom end for connecting the antenna in a broadcast receiving device. The substrate is folded at the conductive trace (4) and mounted on the corner of the PCB. The three dimensional extension of the antenna elements, enables signal gain in three dimensions.
