Abstract: In this paper, geometric dimensions of Cassegrain antenna are designed in the case of the use of axially corrugated conical horn antenna as the feed antenna. The main issue in the design of the Cassegrain antenna is to calculate the dimensions of the feed antenna and the subreflector antenna so that the amount of aperture obstruction can be minimised and the radiation efficiency is increased. After presenting the design method, an illustrative design example is mentioned. Also the effects of selecting different gain values for the feed antenna, on the dimensions and characteristics of the structure is studied.
