Abstract: 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.
