Abstract

A compact, low cost, phased array antenna optical beamformer with element level analog phase (0 - 2 (pi) ) and amplitude control using nematic liquid crystal display-type technology is experimentally demonstrated. Measurements indicate > 6-bit phase control and 52.6 dB of amplitude attenuation control. High quality error calibration and antenna sidelobe level control is possible with this low control power, analog antenna controller. Optical system options using rf Bragg cells or wideband Bragg cells are discussed.
