The present invention relates to a micro remote transceiver and, more particularly, to a transceiver capable of receiving and transmitting signals by itself, and coupling by telecommunication to a remote transceiver, so as to detect an object moving in a high speed. The invention uses a ring antenna made by part of the printed circuit, that forms the oscillator circuit, as a media for transmitting carrier produced by the oscillator circuit and receiving reflected waves. The carrier includes a detecting signal for determining whether the received reflected wave is true or not, and analyzes the environment status. When the transceiver couples to a remote transceiver, according to the field formed by the ring antenna, the transceiver can distribute the signal and receive the command efficiently without always keeping the transceiver ahead of the remote one.
