ABSTRACT:
A windshield antenna for a vehicle is mounted on a central portion of a window glass of the vehicle. The heating wires serve both as a window defogger element and as an antenna for receiving amplitude-modulated (AM) waves. A pair of first and second antenna elements are disposed on right and left sides of the heating wire, each of the first and second antenna elements serving as an antenna for receiving frequency-modulated (FM) waves. These antenna elements can be the same size, yielding improved diversity reception characteristics.
