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".
