Design approach for axially symmetric dual-reflector small cassegrain antenna considering mechanical implementation constraints

An easy-to-do procedure to design axially symmetric small Cassegrain antenna from prescribed geometric parameters is presented. In practice, the design of such an antenna is often restricted by mechanical implementation constraints. In this paper, we justify those geometric parameters of the antenna that can be directly controlled to fulfill these mechanical constraints. The rest of the parameters are assigned reasonably to provide antenna´s optimum performance in gain and etc. Indeed, the design leads to such a smaller antenna.
