Abstract: An assembly comprising a horizontal GPS patch antenna element and a vertical IFF antenna element providing simultaneous high performance IFF communication and GPS reception with minimal IFF to GPS interference. The IFF element can be a monopole element. A second monopole co-linear with the IFF element can provide simultaneous UHF communication. In embodiments, the assembly is a blade that can replace an existing IFF blade on an aircraft or other asset. Separate IFF and GPS connectors can be provided, or a single connecter can be shared using an integral diplexer. Embodiments include a GPS preamplifier integral with the blade. In other embodiments, the IFF element is an annular slot transponder that is centered on the GPS patch element. System embodiments include bandpass filters and/or GPS blanking to further protect the GPS receiver from IFF transmissions.

Abstract: The system and method of global positioning system (GPS) anti-jam (AJ) AJ antennas utilizing a circular array of patch antennas. In some cases the circular array is conformal. The elements are single patch, dual band (L1/L2) and are linearly polarized. A mode former and progressive phase tapers are used.
