Abstract

A modular feed system for a phased array antenna is disclosed. Several contiguous radiative elements in a row (or column) are grouped together by a module network to form a linear array module having two inputs. Excitation of one input produces a constant even distribution at the module output, while excitation of the second input produces a linear odd distribution. The module is adapted to approximate both the average value as well as average slope of a segment of an ideal linear array distribution. A network interconnects a plurality of modules to provide independent sum and difference distributions producing low array pattern sidelobes.
