A novel strategy has been presented to design multi-beam reflector antenna system based on the excitation of a couple of leaky waves by covering the focal plane array with a single thin dielectric layer and tuning the array design to maximize their positive effect. In the worst case scenario of neighboring co-frequency and co-polarized beams an increase of the Geoc of 1 dB over a 6% BW with respect...
The performances of focal plane arrays that implement multi- beam coverage from a single reflector antenna are usually reduced by conflicting requirements on the feed elements. Dense packing is required to minimize the beam separation, while typically large apertures provide the high feed directivity which in turn translates in low spill over losses from the reflector. In this contribution, the use...
