Amplitude and Phase Control with Coarsely Quantized Phase Shifters in Planar Arrays.

Abstract

The purpose of this report is to show that deep nulls can be imposed at specified locations in the phi = 0 deg. pattern cut of planar array antenna patterns using phase-only control of coarsely quantized phase shifters. This is done by using the number of phase shifters available for control in the columns of the array to compensate for the small number of bits of the individual phase shifters. A null synthesis algorithm is derived to calculate the phase shifts to impose nulls in the phi = 0 deg. pattern cut of planar array antenna patterns by matching the pattern of a linear array with nulls imposed at the same locations using continuously variable, composed phase and amplitude control. Results of calculations are presented.
