Abstract :
In this paper a radiating element to be used in dual band, dual polarized Ka band satcom application is presented. The radiator is based on an annular slot which is grounded with vias to form a coaxial structure. Two radiating elements operating around 20 GHz and 30 GHz are nested one into the other to form a dual band antenna. The radiator presents good performances and it is suited for array applications. In fact, it shows good isolation between bands and between polarizations and it makes possible to realize well isolated beam forming networks.
