Uniform and concentrated radio broadcast signals are obtained employing an antenna structure which uses separate antenna conductors on opposite sides of a radio reception area. The antenna conductors perform similarly to the plates of a capacitor. Highly efficient antenna performance results. In a preferred embodiment wherein the antennas are used for radio testing inside a vehicle assembly plant, the track or carrier structure of the vehicle assembly line provides one of the antenna conductors.

Radio frequency broadcast system for enclosed spaces

A motor vehicle antenna system is disclosed for receiving electromagnetically radiated signals in the FM radio broadcast frequency range. The antenna system includes a magnetic current receiving, conformal, substantially rectangular truncated slot antenna. The slot antenna is defined in part by a substantially horizontal portion of a conductive periphery of a window opening of the motor vehicle. The slot antenna is further defined in part by a conductive trace integral with a glazing panel mounted in the window opening. The conductive trace extends horizontally a distance equal to one-half a wavelength in the FM broadcast frequency band. The ends of the trace are effectively connected to the conductive periphery of the window opening. An electrical lead is provided for carrying signals from the slot antenna to a radio receiver, having a first conductor connected to the conductive window periphery and a second conductor coupled to the slot antenna, such as by a network feed structure integral with the windshield, optionally forming an electrical junction with the trace. The side points of the trace are effectively connected to the conductive periphery, e.g., by direct physical connection using an electrical lead, or by providing vertically-extending end traces parallel and proximate to opposite vertical portions of the electrically conductive periphery of the window opening.
