Claims (1)

[Claims for Utility Model Registration] 1. A plurality of antenna conductors for inducing received signals to be supplied to in-vehicle radio equipment, and receiving signals of a diversity reception method from the received signals induced by the plurality of antenna conductors. An automobile window glass antenna comprising a diversity circuit formed on a glass surface. 2. A plurality of antenna conductors for inducing received signals to be supplied to in-vehicle radio equipment, a diversity circuit that forms received signals of a diversity reception method from received signals induced by the plurality of antenna conductors, and the above. 1. A windowpane antenna for an automobile, comprising a tuner circuit on a glass surface that selects a signal of a receiving frequency based on frequency information given from a device using radio waves and tunes the signal to its carrier frequency.
