Summary:
An X-Ka band high gain antenna configuration is discussed in which the gain is improved by using a reflect-array on the sub-reflector. The implementation is for a dual reflector antenna with a dual frequency feed. Experiences in Spanish institutions have been combined, like reflect-array developments (UPM), feed design and technology (Rymsa) and design and technological manufacturing processes (EADS CASA Espacio). Control of reflection properties (specific design of reflect-array) assists to obtain good performances for an antenna configuration. It allows making efficient use of the antenna aperture for two different bands for high-gain, whilst controlling separate bands.
