An antenna structure for vehicles capable of minimizing the distance between a first contact member and a signal processing circuit and ensuring stable antenna performance without using a connection line of a lengthy wire rod is provided. To realize this advantage, an antenna element is disposed on a rear window glass, and the first contact member is disposed at an end of the antenna element. Further, an amplifier case having an attachment flange facing the rear window glass is fixed to a roof panel, and the signal processing circuit is disposed in the amplifier case at a position sandwiching the attachment flange.

Antenna structure for vehicles

A glass antenna for an automobile that can improve sensitivity in an FM broadcast band and a frequency band region higher than the FM broadcast band, in which a defogger and an antenna conductor are provided in a rear window glass sheet . A vertical portion of the antenna conductor crosses or overlaps a plurality of heater strips , and the antenna conductor and the heater strips are laid one upon another by interposing an insulation layer in the crossing or overlapping portion.

Glass antenna for an automobile

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 3,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.
