ABSTRACT:
A vehicle slot antenna system including a vehicle having generally interconnected metal parts, a window frame integral with the vehicle, and a connector having two electrically conductive conduits each extending to the window frame from an impedance matching module in communication with a radio signal generator and/or receiver. The window frame has first and second substantially parallel metal border members whose perimeters form a slot and wherein perimeter sites of a window can be retained, with the slot being functional as a slot antenna. Such functionality is achieved through having one conduit of the connector in communication with the first border member of the window frame and the other conduit thereof in communication with the second border member of the window frame. The vehicle functions as a contoured metal ground plane having sufficient metal-to-metal interconnections to enable window frame utility as a slot antenna. The present invention additionally includes methodology for transmitting radio signals or for receiving radio signals by employing the slot antenna system in the vehicle and appropriately powering transmission or reception, respectively, of a signal generator or receiver device. The system here defined permits usage of integral structures of a vehicle without invasive mounting requirements or significant antenna visibility.
