As wideband multibeam antennas, because of the advance in printed-circuit antennas and MMIC, active phased arrays tend to be alternatives to reflectors and lenses. However, this makes the Beam Forming Network very complicated, heavy and expensive. Recenfly the applicafion of optical or photonics technology to microwave array antennas has been studied. Instead of full use of microwave components, optical components such as lenses and fibers are employed to control the phase and amplitude weights for each element of an array. In this paper, an optical feed experimental arrangement for two-multibeam microwave array antennas is demonstrated. Only the lasers equivalent to the number of microwave beams and the sampling fiber array whose element equals that of array antenna are required, and individual optical phase and frequency shifters for each beam are not necessary.
