ABSTRACT:
A radiating element for a radar array has a conductive shell defining a cavity having an aperture; a dielectric material at least partially covering the aperture, and an excitation device coupled to the cavity for exciting the cavity in a radar band. A radar array has an extended ground plane having openings therein and a radiating element situated in each of the openings, the radiating elements having a conductive shell defining a cavity with an aperture therein, dielectric material at least partially covering the aperture, and an excitation device coupled to the cavity.
