COMMUTATING FEED FOR CIRCULAR ARRAY ANTENNA AND ITS APPLICATION TO THE LES

Abstract

A commutator for circular antenna array is described using multi- throw switches fed in parallel through a power divider. The excitation phases of the elements can be controlled by phasing elements located between the power divider and the switches. In applications requiring excitation of only a few radiators at a time, each phasing element might simply be a diode together with tuning reactances. Application of the commutator and phasing scheme to a step- scanned antenna for LES-5 or 6 is described.
