Automobile antenna

Claim 1

A vehicle antenna system responsive to both electrostatic and electromagnetic components of a radio signal and presenting an optimum impedance to associated radio circuits, including: an electrically conductive vehicle body having at least one window opening therein to form a conductive edge; a first conductor series connected with a first condenser to form a first tuning combination, said first tuning combination being electrically coupled between oppositely disposed points along said conductive edge, said condenser having a magnitude of capacitance sufficient to produce in the medium wavelength radio band electrical resonance of a body loop including at least a portion of said conductive edge; a plurality of intercoupled, electrically conductive members serially disposed on said window to form at least one antenna element primarily responsive to the electrostatic component of an impinging radio wave; at least one of said plurality of intercoupled, electrically conductive members being physically closely proximate to said first conductor and parallel thereto but conductively isolated therefrom, whereby capacitive and inductive coupling of radio signals between said first conductor and said at least one of said plurality of intercoupled, electrically conductive members, occurs; and an output conductor coupled to one of said at least one of a plurality of intercoupled, electrically conductive members proximate to said first conductor.
