Abstract
A mobile antenna unit for use in the FM broadcast band which is adapted to be mounted on the windshield of the vehicle and which provides a gain and directivity pattern similar to those of an external whip antenna. The antenna element takes the form of a conductor mounted near one of the pillars supporting the windshield. The pillar appears electrically as an inductor and the conductor as a capacitor. By properly dimensioning and spacing the conductor with respect to the pillar, resonance is achieved in the FM broadcast band.
