ABSTRACT:
A directive antenna having plural antenna elements is arranged in a parasitic antenna array. Frequency selective components are connected to an active antenna element. Weighting structures are connected to passive antenna elements positioned substantially equidistant from the active antenna element. The active and passive antenna elements are connected by a space-fed power distribution system to produce independently steerable beams having spectrally separated signals.
