ABSTRACT:
A first resonance is generated by the inductance of a first coil connected between a first antenna conductor in a window glass sheet and a receiver and the impedance of the antenna conductor, and a second resonance is generated by the inductance of a second coil connected between a second antenna conductor and an automobile body as the earth. The antenna conductor and the antenna conductor are in a capacitive coupling relation, whereby signals in different broadcast band: a low frequency band and a high frequency band, are well received.
