The present invention relates to an antenna for switching between a right-turning circular polarization antenna, a left-turning circular polarization antenna, and a right-turning circular polarization antenna and a left-turning circular polarization antenna according to a predetermined switching control signal. At the time when communication is first performed at the switch transmitting station, the right transmitting circularly polarized antenna and the left rotating circularly polarized antenna are repeated by a transmitting unit and a receiving station repeatedly transmitting a predetermined antenna switching data pattern by using the right rotating circularly polarized antenna and the left rotating circularly polarized antenna. Receiving the data transmitted from the transmitter and generating a switching control signal for connecting an antenna having a low error rate between the received data of the two antennas and the predetermined antenna switching data pattern to be applied to the antenna switching switch. It consists of a. Therefore, it is possible to transmit the high speed data by reducing the time delay of the received radio wave.
