Abstract : During this period, the element investigation was completed and the conical horn operating in the TE sub 11 mode was selected. Both solid and artificial dielectric lenses were successfully developed for use in correcting the spherical aberration in the horn aperture. The artificial dielectric lens has the advantage of greater power handling ability and less weight. Radiation patterns of the array were computed using the conical horn element pattern. The array feed system was selected after studying two general approaches: an optical system, and a constrained system using beamforming networks. A novel constrained feed system was developed which is well suited for exciting ring arrays -- this approach is recommended.
