摘要： 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. Upon receiving either the first or second interrupt indicator at the system controller, the system controller switches the information output select device between the national broadcast information and the local broadcast information. A method for providing a seamless transition between national broadcast information and local broadcast information for a receiver is also disclosed. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

摘要： 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.

摘要： 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.
