Claim Text:
1. An ultra-wideband antenna assembly comprising: an electromagnetic reflective structure for reflecting electromagnetic waves over an ultrawide bandwidth: the electromagnetic reflective structure configured to to reflect electromagnetic waves in a first direction and comprising first, second and third groups of differently sized patches configured to resonate at different closely spaced frequency bands, thereby providing an ultra-wide band operation: a printed circular monopole antenna supported by a dielectric substrate and further comprising an electrically conductive coplanar waveguide designed for the 700-3000 MHz band in electrical communication with the antenna, the electrically conductive coplanar waveguide comprising two ground planes supported by the dielectric substrate; the printed circular monopole antenna being operatively associated with the electromagnetic reflective structure such that electromagnetic waves emitted from the printed circular monopole antenna towards the electromagnetic wave reflective structure are reflected back by the electromagnetic reflective structure in the first direction: the antenna being substantially planar and extending in a first plane: the first direction being substantially perpendicular to the first plane: and at least one director operatively associated with the antenna for focusing the electromagnetic waves transmitted by the antenna in the first direction: the at least one director being substantially planar and extending in a second plane wherein the second plane is substantially parallel to the first plane.
