Abstract
An antenna system for transmitting radio waves in the same direction as the direction of arrival of incoming radio waves. The arrival direction is detected by a fast Fourier transform processor. The transmitting direction is adjusted by phase-shifting radio waves from a feeder on the basis of the detected arrival direction. Further, signals in the system are transmitted through optical fibers in order to decrease the processing time.
