    Abstract: A communications system (10) and method (100) thereof are provided, wherein the system (10) includes a first receiver (14). The first receiver (14) includes at least one antenna element (A 1 ) configured to receive the first signal having a first polarization, and a combiner (20) in communication with the at least one antenna element (A 1 ), wherein the combiner (20) enhances the first signal and minimizes a second signal having a second polarization that is different than the first polarization of the first signal, such that an output (31) is emitted by the first receiver (14) based upon the received first signal. The first receiver (14) further includes a beam steerer (22) in communication with the combiner (20), wherein the beam steerer (22) is configured to steer an antenna beam of the at least one antenna element (A 1 ) in order to minimize reflection of the second signal, such that the second polarization of the second signal remains different than the first polarization of the first signal.

    Abstract: An antenna unit (10, 100, 200) is disclosed. The antenna unit (100, 200, 300) includes a patch antenna element (12, 102, 202) with a dielectric substrate (14, 104, 204) positioned on a circuit board (16, 106, 206). A parasitically enhanced perimeter (18, 108, 208) extends from the circuit board (16, 106, 206) and encompasses the patch antenna (12, 102, 202) to utilize surface waves in order to enhance low-elevation terrestrial antenna performance.
