摘要： PURPOSE:To avoid the antenna coupling circuit from being largely projected from a face of glass and to reduce disturbance of the visual field by providing an outer circumference conductor which forms an inductance between a meandering conductor and an opposed electrode having a wider area than an area of the meandering conductor and forms a capacitance between itself and the opposed electrode to the antenna coupling circuit. CONSTITUTION:A meandering conductor 10 shown in an ellipse in figure, an opposite electrode 20 and an outer circumference conductor 30 are provided to the antenna coupling circuit and they are printed on a printed circuit board. The opposite electrode 20 is an electrode connected to one end 10a of the meandering conductor 10 and having a wider area than the area of the meandering conductor 10. The outer circumference conductor 30 is a conductor connecting to the other end 10b of the meandering conductor 10, forming an inductance L with the meandering conductor 10 and forming a capacitance C with the opposite electrode 20. Thus, the circuit is not largely projected from the face of glass and the disturbance of a visual field is less.

摘要： PURPOSE:To mount an antenna without making a hole to a car body by providing an FM resonance circuit comprising a spiral coil and a capacitor, a band pass filter, a capacitor electrode and an AM impedance converter so as to form the antenna. CONSTITUTION:Resonance circuits 11, 12 resonated in the FM frequency are formed to both the antenna and output sides in the operation relating to an FM frequency signal to form a dual tuning circuit by means of electromagnetic coupling. Thus, the FM frequency band is covered and its coupling circuit is formed to be in operation at a broad band frequency. Then the coupling static capacitance is formed by capacitor electrodes 13, 14 in the operation relating to the AM frequency signal. An impedance converter employing a FET is inserted to an output terminal of the coupling static capacitor, a signal is extracted by using a high impedance input as a low impedance output and connects to a feeder 41. Thus, the capacitance split loss is almost eliminated and the AM frequency signal is practically received.
