Optimal parameters of Cassegrain antennas
Abstract
An expression for the directive gain of an axisymmetric Cassegrain antenna is obtained which takes into account energy spillover beyond the reflector, shading by a small reflector or feed, and illumination of the edge of the large reflector by a penumbral field. Optimal values of the main parameters of the antenna are determined with respect to the maximum directive gain.
