Abstract

A new shaped subreflector geometry for EMC oriented Cassegrain system is presented. The idea is to deform the classical hyperboloidal surface to reduce the spillover and the crosspolarization. The high gain antenna obtained can be used as a test antenna to detect external noises or to reduce the cross-polarization in a telecommunication system. Experimental validations resume the excellent results obtained for a 60 cm antenna/80 mm subreflector system in the 37-40 GHz frequency range. Different kind of antennas have been designed and now produced
