Abstract
A dielectric resonator element array (DRA) antenna system that is small, compact, has high gain in the direction of intended communication, minimized interference in unintended directions of communication and a wide bandwidth. The antenna system comprises a ground plane, a feed structure, a beam shaping and steering controller, a mounting apparatus, an array of dielectric resonator elements and a radome that is close to or in contact with the array. The mounting apparatus preferably is configured so as not to appreciably increase the size of the system when mounted. The controller receives and processes information relating to one or more of object latitude, longitude, attitude, direction of travel, intended direction of communication and unintended directions of communication. The controller processes this information and determines excitation phase for the array elements.
