Abstract
The unique features of radiation pattern formation in spherical mirror antennas are determined. It is shown that in antennas of this type there is a possibility of doubling directivity by placement of the feed at the paraxial focus. Equations are developed for calculation of the optimum feed placement, effective aperture radius, directional pattern width, and side lobe level. It is shown that side-lobe radiation from a spherical mirror antenna is formed by geometric optical reflection of the feed field on the peripheral portion of the mirror.
