1. A multiband antenna comprising:
- a ground plane; and
a radiating structure coupled to said ground plane, said radiating structure further comprising;
a primary radiator having a predetermined first resonant frequency band; and
a sheet conductor coupled to said primary radiator and spaced from said ground plane, said sheet conductor being so configured as to cause said radiating structure to have a second predetermined resonant frequency band.

21. A method of transceiving signals in multiple frequency bands, such method comprising the steps of:
-
providing a generally conical structure operating as an antenna to communicate signals over a first frequency range, said generally conical structure having an aperture defined by an end surface thereof;
forming first and second conductive surfaces coupled to said end surface and shaped to communicate signals over a second frequency range, said conductive surfaces being generally coplanar with the end surface;
providing a ground plane disposed in generally parallel spaced relationship relative to said conductive surfaces; and
forming at least two support structures coupled to said conductive surfaces, for supporting said conductive surfaces at a distance (d) from the ground plane. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
