The increasing of operation range of local positioning system

Abstract

The way of increasing of operation range of homodyne system of RFID and positioning is discussed. It is proposed to use two microwave amplifiers at transponder design. The first is the one-port microwave amplifier (regenerative amplifier) and the second is the part of transponder's active antenna. This part of the active antenna is the regenerative microwave amplifier which is built in the antenna design. The operation of active antenna in receiving and transmitting modes is considered. These modes can be realized simultaneously. There is no need to implement the switching between these modes.
