摘要： 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.

摘要： A window glass antenna system includes a defogging heater pattern disposed on a window glass pane and being operable also as an AM broadcast receiver antenna, an impedance matching circuit having two inductors for respectively causing series resonance and parallel resonance of AM broadcast signals fed from an output of the heater pattern and being designed to supply the AM broadcast signals to an associated radio receiver, and at least one capacitor disposed between the heater pattern output and the impedance matching circuit for blocking induced noises of AM frequency band. With this arrangement, it becomes possible to significantly attenuate noises of AM frequency band to be induced into the heater pattern, without attenuating received signals of AM broadcast, whereby AM broadcast radio reception of good S/N ratio is enabled.

摘要： The present invention provides a glass antenna device for mobile communication with suitable impedance matching for two different frequency bands. In this antenna device, the ends of a substantially straight first radiation antenna pattern and a second radiation antenna pattern are coupled by a coupling pattern that is substantially perpendicular to the first and second radiation antenna patterns. The longitudinal direction of the coupling pattern is arranged substantially in parallel to the ground. The length of the first radiation antenna pattern is different from the length of the second radiation antenna pattern. A rectangular grounding pattern is arranged below this U-shaped antenna pattern. A core conductor of a coaxial cable is connected to the U-shaped antenna pattern, and a braided conductor of the coaxial cable is connected to the grounding pattern. An impedance-adjusting pattern is provided on a lateral portion of the grounding pattern.
