Abstract

This work presents significant improvement on Side Lobe Level optimization for self-supported sub-reflector fed systems of compact reflector antennas. The case study presented shows the experimental results of a 1200mm reflector system that operates at Ku band for Satellite Communication Systems. Besides, de sub-reflector is supported by a radome made of composite material of aramid kevlar and foam. The radome supports an elliptical sub-reflector that illuminates the main reflector with the field fed by a one choke feed horn. The technique used for the reduction of the Side Lobe Level consist on the reduction of the current of the fundamental and first higher mode that are scattered from the main and sub-reflector to the mast and sub-reflector metallic surfaces.
