Abstract
PURPOSE:To execute stable communication between road vehicles regardless of a traveling traffic lane and to prevent an appearance from being spoiled by providing the antenna coil of a loading antenna for inductive radio with being received in two door mirrors. CONSTITUTION:The output of right and left antenna coils 4 and 5, which are padded into door mirrors 2 and 3, is connected to a coupling transformer 11 to constitute a coupling circuit in a communicating equipment 6 by cables 9 and 10. At such a time, since the connection is executed so that both outputs can be added at the same phase with considering the coiling direction of the antenna coils 4 and 5 and the polarity of the input of the coupling transformer 11, a synthesizing output, which is added phase by the coupling transformer 11, is received through a transmission and reception switching circuit 12. The transmission from the communicating equipment 6 is also executed through the switching circuit 12 in the same way.
