Abstract
An antenna array includes a plurality of radiating elements disposed on a layer that is situated above an egg crate structure that is formed of interconnected dielectric panels. In some embodiments, balun circuitry is disposed on at least some of the dielectric panels of the egg crate structure for use in feeding corresponding radiating elements of the array in a balanced manner. Ground plane blocks may also be coupled to some or all of the dielectric panels to provide circuit shielding and/or to form a ground plane for the array antenna.
