Sidelobe Cancellation for Uniformly Excited Planar Array Antennas by Controlling the Side Elements
A sidelobe cancellation over a wide angular range for the uniformly excited planar array is proposed. The approach is to readjust the amplitude and phase excitations of the boundary elements only, while keeping the rest of elements unchanged.

description | A sidelobe cancellation over a wide angular range for the uniformly excited planar array is proposed. The approach is to readjust the amplitude and phase excitations of the boundary elements only, while keeping the rest of elements unchanged. Simple expressions for computing the required amplitude and phase excitations of these boundary elements are given. The technique simplifies the feed network as it requires only one attenuator and two phase shifters. Simulation results show that cancellation of sidelobes across a wide angle can be obtained. |
