Abstract
A design procedure is described for a Cassegrain antenna employing a dielectric cone feed. Modal methods are used to determine the cone geometry, while a geometric-optics method is used to determine the subreflector profile. Good agreement is observed between measured and predicted radiation patterns for a 1.2 m-diameter parabolic antenna utilising the feed and operating at a frequency near 11 GHz.
