  • High frequency capacitive coupling antenna for vehicles
    Patent number: 7592960
    Abstract: An antenna system includes a detachable assembly including a circuit board that is connected to a cover by a resilient member. A bezel is adhesively attached to the glass of a vehicle having conductive antenna elements on the vehicle glass. The bezel includes guide surfaces and locating surfaces that accurately position the circuit board and antenna feed wire relative to the vehicle glass. The cover and circuit board can be detached from the bezel for servicing of the circuit board, and the guide and locating surfaces of the bezel provide for accurate positioning of a replacement detachable upper assembly during servicing/repair of the antenna system.

  • Antenna module assembly
    Patent number: 6930643
    Abstract: A fastening structure for an antenna module assembly is disclosed. The fastening structure for an assembly includes a cover, a gasket inner seal, a circuit board including at least one antenna element, and a base. The gasket inner seal is placed over the circuit board. The gasket inner seal and circuit board are intermediately located between the cover and the base. The base includes a plurality of beveled snap-tab receiving portions integrally located about a base perimeter. The beveled snap-tab receiving portions engage an inner perimeter of the cover defined by flexible snap-tabs to fasten and matingly secure the cover to the base.
