FREQUENCY SELECTIVE SURFACE ZONING TECHNIQUE TO REDUCE THE COMPLICATION IN DESIGN FROM LARGE RANGE OF ILLUMINATION INCIDENT ANGLES

摘要

A method for providing frequency selective surface zoning includes selecting a location for positioning a frequency selective surface (FSS) panel along a support arm of a reflector antenna system, and positioning a second feed horn on the support arm on an opposite side of the FSS panel. A number of unit cells are used to populate the FSS panel, and metallic patterns are formed on each unit cell. Multiple zones are subsequently defined on the surface of the FSS panel. Each zone is optimized for a predetermined range of incident angles.
