Abstract

The problem of synthesizing a linear array generating a shaped beam pattern with M filled s has 2M alternative solutions. In this study we examined their bandwidths as regards compliance with pattern quality or input impedance requirements in the presence and absence of a backing ground plane. Placing a ground plane behind the antenna almost doubles sidelobe level bandwidth.
