  • Antenna adapted for placement in the window of a vehicle
    Patent number: 5712645
    Abstract: An antenna adapted for placement in the window of a vehicle includes a flexible substrate having a pair of opposing surfaces, at least one of which is provided with electrically conductive metal traces in the form of a pattern configured to receive and transmit one or more electromagnetic signals. The pitch, trace width, and thickness of the metal traces are selected such that the antenna has an area-averaged resistivity of no greater than about 1 ohm/square for a pre-determined area-averaged transmission value in the visible region.
