Abstract
One embodiment discloses an antenna structure. An antenna structure comprises: a transmit antenna element comprising a plurality of transmit antenna sub-elements; a receive antenna element comprising a plurality of receive antenna sub-elements, wherein the transmit antenna element and the receive antenna element are orthogonally-polarized with respect to each other; a ground plane defining a reflector for the antenna structure; at least one electronic component coupled with the ground plane, the at least one electronic component comprising: a transmit balanced to unbalanced (BALUN) circuit configured to split a transmit signal from a transmitter into two balanced transmit signals, wherein the plurality of transmit antenna sub-elements are coupled to the transmit BALUN; and a receive BALUN circuit configured to combine feeds from the plurality of receive antenna sub-elements into a receive single output to a receiver.
