Abstract
This document discloses a reflector antenna system with movable MIMO multiple feeds and adaptive field focusing method for wireless communication in multipath fading environment; the system comprises antenna reflector, multiple feeds, the equal number of the signal receiving channels and signal transmitting channels to the feeds, all the channels are capable to measure and adjust the amplitude and time delay of signals, and the method for amplitude and time delay adjustment of the powered signals. In signal receiving mode the antenna system makes the signal components arrived through unknown multipath superimpose synchronously; in signal transmitting mode, the system let the wave components radiated from different transmitting channels superimpose synchronously, realizing adaptive field focusing at the antenna of the communication target. This antenna system is suitable for point to point wireless communication in wireless propagation environment with multipath fading effect, showing remarkable improvement of SNR of the signals transmitted and received.
