Abstract: A system for amplifying GPS and satellite digital radio signals is provided. The system includes a GPS antenna configured to receive signals transmitted by a GPS satellite, and a satellite digital radio antenna configured to receive satellite digital radio signals. The system also includes an amplifier that is electrically coupled to the GPS antenna and satellite antenna. The amplifier is configured to amplify GPS and satellite digital radio signals received by the satellite digital radio antenna and GPS antenna. A method for amplifying GPS and satellite digital radio signals is also provided.

Abstract: An integrated patch antenna is disclosed. The integrated patch antenna receives at least a first and second band of signals. The integrated patch antenna includes a bottom metallization and first and second upper metallizations disposed about a dielectric material to receive the first and second signal bands. The first and second signal bands may be, for example, a satellite digital audio radio systems (SDARS) band and a global positioning system (GPS) band.

Abstract: An antenna system for a vehicle including a rear windshield is disclosed. The antenna system comprises a global positioning system (GPS) antenna unit including a radiating element electromagnetically coupled to an excitation element about the rear windshield glass.

Abstract: An antenna disposed on glass including first and second spatially separated grid portions is disclosed. The first grid portion is electromagnetically coupled to the second grid portion to provide reception of AM and FM signals.

Abstract: An antenna including a first FM portion and first and second AM portions. The first AM portion at least partially circumscribes the first FM portion and the second AM portion at least partially circumscribes the first AM portion and at least partially circumscribes the first FM portion.

Abstract: The present invention provides an antenna unit that eliminates the need for an EMI shield to protect the sensitive components of the antenna unit's circuit board from EMI. The antenna unit includes a planar member composed of a material operating as a ground plane for the antenna unit, the ground plane defining a cavity; a circuit board secured to the ground plane, the circuit board including a platform and at least one circuit board component, the platform covering the cavity so as to enclose the circuit board component within the cavity, and an antenna positioned adjacent to the platform and in communication with the circuit board.

Abstract: An antenna system for a vehicle radio integrated with the defogger heating elements in a window that provides enhanced impedance matching without requiring lumped matching components. The antenna system includes a vehicle window, a conductive grid embedded in the vehicle window and having a plurality of horizontal and generally parallel conductive elements, and first and second bus bars connecting the grid at opposite ends. The antenna system has first and second vertical conductive elements embedded in the vehicle window and arranged substantially orthogonal to the horizontal conductive elements. Tuning elements are coupled to each of the first and second vertical conductive elements and are substantially orthogonal thereto. The tuning elements have a length selected so as to substantially match characteristic impedance of an RF signal path. The horizontal heating elements are engaged for heating the vehicle window during a heating operation, and also serves to receive radio signals for the radio.
