Dual Ka-Band Multiple Beam Reflector Antenna for Western European Coverage

This paper presents a dual-band multiple beam reflector antenna for a Western European coverage. The dual configuration comprises a wire grid sub-reflector and a polarising main reflector that converts the linearly polarised incidence into circular polarisation with orthogonality between bands. The good performance of the wire grid and the polarising main reflector ensure far-field axial ratio values at the −3 dB region below 1 dB on average without any previous optimisation.
