Abstract:
An antenna for providing multiple antenna patterns from a plurality of RF illumination signals having differing electrical characteristics from a single reflector antenna comprising: a concave reflector body formed of a plurality of zones, each of the zones is configured to reflect a portion of one of the RF illumination signals and a first of which is configured to be non-reflective to one of the RF illumination signals having a different electrical characteristic than the electrical characteristic of the RF illumination signal reflected by the first zone, at least one of said zones is both a frequency selective and a polarization sensitive zone; an illumination source configured to illuminate said reflector body with the plurality of RF signals; and absorbing material coupled to said reflector body and operative to absorb a non-reflected portion of one of said RF illumination signals, each of said zones reflecting one of the RF illumination signals, each reflected RF signal generating one of the plurality of antenna patterns.
