Design of Radome-Covered Slot-Array Antennas Loaded with Parasitic Dipoles for Circular Polarization at Ka Band

This paper describes the procedure followed to design a large array of resonant shunt slots loaded with parasitic dipoles to achieve circular polarization. The array is covered with a multilayer radome. The modelling technique uses specialized Green's functions for both the multilayer region and the rectangular waveguide region and the method of moments. The design procedure is based on the so-called "equivalent self-admittance method".
