  • Patent number: 8005418
    Abstract: An antenna system is provided having switched directional antennas. The antenna system includes a first antenna for receiving signals within a first directional coverage zone, and a second antenna for receiving signals within a second directional coverage zone. According to one embodiment, the first and second antennas are located on a vehicle. The system has a device to detect orientation of the vehicle. The system further includes a receiver having control circuitry for controlling selection of the signals received from the first and second antennas based on orientation of the vehicle, location of one or more sources, and antenna coverage zones for the first and second antennas.

  • Patent number: 7606327
    Abstract: A receiver is disclosed. The receiver includes a first antenna, a second antenna, a system controller, a national broadcast demodulator, a local broadcast demodulator, and an information output select device. The first antenna for receives a signal from a satellite that contains information of national interest. The second antenna receives a signal from a land-based transmitter that contains information of local interest. The national broadcast demodulator is coupled to the first antenna and the system controller. The national broadcast demodulator provides a first interrupt indicator to the system controller. The local broadcast demodulator is coupled to the second antenna and the system controller. The local broadcast demodulator provides a second interrupt indicator to the system controller.

  • Patent number: 6999030
    Abstract: A planar microstrip antenna includes one or more aperture-fed circular patch radiating elements capacitively coupled to respective parasitic strip elements. The circular patches are symmetrically disposed above respective ground plane apertures, and the parasitic strip elements are annular sectors that are co-planar and concentric with the circular patches, and placed adjacent to the periphery of each circular patch. The disclosed geometry enhances the input impedance bandwidth, and significantly reduces off-boresight radiation variability to provide beam directivity that is more uniform over both frequency and direction.
