Abstract
Systems and methods which utilize a symmetrical partially coupled microstrip slot feed patch antenna element configuration to provide highly decoupled dual-polarized wideband patch antenna elements are shown. Embodiments provide a microstrip slot feed configuration in which a slot of a first signal feed is centered with respect to the patch and further provide a microstrip slot feed configuration in which slots of a second signal feed are symmetrically disposed with respect to the center of the patch and at positions near the edges of the patch. The microstrip feed utilized in communicating signals with respect to the slots of the second signal feed is adapted to provide signals of substantially equal amplitude and 180° out of phase with respect to each other according to embodiments. The second signal feed configuration utilized according to embodiments provides partial coupling between the patch and the second signal feed.
