Abstract
The realisation of a polarising main reflector for use in a W-band Cassegrain antenna system is described. The main reflector has rectangular grooves cut in its entire surface to change the polarisation from linear to circular. In addition, the use of the FD-TD (finite difference time domain) method for predicting the performance of an axisymmetric dielectric cone subreflector is shown.
