輛側において受信することが必要となつている。 In railways, monorails, new transportation systems, etc. in which vehicles operate on a specific passage, the passage is divided into sections at predetermined distances, and the presence of a vehicle in each section is detected before a subsequent vehicle enters the same section. In order to prevent this, traffic lights are controlled, and following vehicles are controlled to speed and stop at fixed points.For this purpose, a signal indicating the presence of a vehicle is transmitted from the vehicle side, and this signal is received on the ground side. On the other hand, it has become necessary to transmit various control signals from the ground side and receive them at the vehicle side.

In addition to providing a loop antenna L extending over the passage over the entire section, a ground receiver RX G is connected via a branching filter H. and ground transmitter TX G are connected to loop antenna L, and on vehicle V,
An on-vehicle transmitter TX V and an on-vehicle receiver RX V are provided, and a cored or air-core coiled transmitting antenna L T and receiving antenna L R are respectively provided facing the loop antenna L.

を生じている。 However, the power applied to the transmitting antenna L T
10W, whereas the power handled by the receiving antenna L R is extremely small at about 0.1 mW .
Since the RX V etc. are manufactured for low power use, if the signal emitted from the transmitting antenna L T is induced directly to the receiving antenna L R by mutual induction, the receiving antenna L R and the on-board receiver RX V may become too large. The transmitting antenna L T and the receiving antenna may be damaged due to the application of electric power, and the received signals may be interfered with by the transmitted signals, making it difficult for the onboard receiver RX V to receive them properly. L T and L R must be placed at a considerable distance from each other, and a shield S must be provided between the two, making installation of the transmitting antenna L T and receiving antenna L R cumbersome, increasing the number of man-hours for installation work, and reducing the required time. This has disadvantages such as high costs.

The present invention provides a transmitting/receiving antenna in which mounting of each antenna is extremely easy by integrally forming the antennas surrounded by an insulating material.

となる。 For the above, as shown in Fig. 3, a cancel coil C 3 is provided on the coil C 2 side, and each coil C 1 to
Assuming that the winding direction of C 3 is as shown in the figure, and that the current I 1 also passes through the cancel coil C 3 ,
The cancel coil C 3 generates a magnetic flux Φ 3 in the opposite direction to the magnetic flux Φ 1 , which induces a current I 3 in the coil C 2 , which has the opposite polarity to the current I 2 .
このため、コイルC2とキヤンセルコイルC3と
の巻線比および相互誘導量を、電流I2とI3とが等
しくなる値に定めれば、次式が成立する。 Therefore, if the winding ratio and the amount of mutual induction between the coil C 2 and the cancel coil C 3 are set to values that make the currents I 2 and I 3 equal, the following equation holds true.
I2−I3＝０ …(1)
