Phase-Only Nulling with Coarsely Quantized Phase Shifters

Abstract

The purpose of this report is to show that deep nulls can be imposed at specified locations in planar array antenna 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. Null synthesis algorithms are derived to calculate phase shifts to impose nulls in the phi equals 0 degrees pattern cut of planar array antenna patterns. Results of calculations are presented in this report. Keywords include: Planar array antennas, Phase quantization, Phase-only weight control, and Null synthesis.
