Overlapped subarray antenna feed network for wireless communication system phased array antenna

摘要

An antenna phased array comprising a two-input four-output beam forming network where each of the four outputs is coupled to one of four antennas. The antennas generate beams of signals from signals applied to the inputs of the beam forming network. The antennas form two sub-arrays of antennas each comprising three antennas. The beam forming network is designed such that the beams generated by each of the sub-arrays form aggregate beams having desired beam widths. Adjacent antennas are spaced a certain distance apart such that beam steering can be performed by combining the two aggregate beams.
