The effect of a reflector support boom on the antenna far field pattern

Abstract

analysis is carried out in two steps: First the magnetic f ie lds on the surface of the ref lector are determined. These f ie lds a re due to direct radiat ion from the feed as well as scat ter ing from t he reflector support boom. Next, t h e resulting physical optics currents are integrated over the reflector surface to obtain the far f ie ld radiat ion pat tern of the antenna/boom combination.
