Abstract

A pair of antenna conductors are formed on upper and lower blank portions outside an area where defogging heater wires are attached on a window glass of a motor vehicle.
One of the antenna conductors is RF-coupled with the defogging heater wires and a feed terminal thereof is located at a lateral side of the glass. The other antenna conductor has a feed terminal located at another lateral side of the glass. A pair of reception signals complement with each other in directivity due to asymmetric characteristic of the antenna conductors and are used in a diversity reception system for obtaining a nondirectional reception characteristic.
