Claims

[Scope of utility model registration request]

A vehicle antenna capable of transmitting/receiving CB waves and receiving FM waves and AM waves; a common terminal of this antenna is connected to a feeder, a first branch terminal is connected to a CB wave transmitter, and a second branch terminal is capable of receiving FM waves and AM waves. -AM- A duplexer connected to a radio receiver, and the duplexer includes a first signal transmission path connecting the common terminal and a first branch terminal, and a first signal transmission path connecting the common terminal and the first branch terminal. a second signal transmission path connecting the two branch terminals; It has a resonant circuit that resonates in series with the center frequency of the CB wave and has a composite reactance that can cancel out the actance component of the impedance on the antenna side, and has an FM wave attenuation effect and an A
A second resonant circuit consisting of a series circuit of an inductive element and a capacitive element that has an M-wave blocking effect, and a CB
An L-type matching circuit in which an inductive element and a capacitive element are connected in an L-shape is connected in series so as to match the input/output impedance of the wave transmitter, and an FM A third resonant circuit that passes the wave and the AM wave and substantially blocks the passage of the CB, and an adjustment capacitance element that adjusts and sets the capacitance value at the input end of the AM wave receiver to a specified value are connected in series. 1. An antenna device for a vehicle, characterized in that the antenna device is an antenna device that is interposed and connected to each other.
