  • Conformal electro-textile antenna and electronic band gap ground plane for suppression of back radiation from GPS antennas mounted on aircraft
    Patent number: 10439277
    Abstract: An antenna system having reduced back radiation is disclosed. The antenna system includes an antenna and ground plane. The antenna includes electro-textiles and is configured to operate in at least the frequency range between 1.1-1.6 GHz. The ground plane includes electro-textiles and is configured to operate as a frequency selective surface with electronic band gap characteristics to suppress edge and curved surface diffraction effects. In this system, the antenna and ground plane are configured to be located on a curved surface and to radiate with a directional radiation pattern having attenuated back lobes.

  • Ultra-high frequency (UHF)-global positioning system (GPS) integrated antenna system for a handset
    Patent number: 8749439
    Abstract: Embodiments provide an integrated antenna system that enables dual-use operation (e.g., communications and navigation). In an embodiment, the integrated antenna system includes a sleeve monopole antenna system and stacked shorted annular ring (SAR) patch antenna system, which are compactly integrated to fit on a military handset or a smart phone. In an embodiment, the integrated antenna system enables communication in the 225-450 MHz Ultra-High Frequency (UHF) band and reception of various Global Navigation Satellite System (GNSS) bands.
