Abstract :
A new optical feed for transmitting multibeam microwave array antennas is proposed by using spatial Fourier optical processing. The system design is given with consideration of generating overlapping multiple beams. A two-beam experimental optical feed is demonstrated. Two RF signals of 800 MHz and 1 GHz with different phase distributions for feeding to array antennas are obtained and measured spatially.
