ABSTRACT:
A low cost and low profile antenna for commercial use, either in a fixed or mobile condition is disclosed. The antenna has a generally flat circular plate that rotates to seam the azimuth direction. A plurality of radiation elements are positioned on the surface of the circular plate. The received signals are multiplexed, digitally converted, digitally beamformed, and then transferred to a digital receiver.
