Abstract :
A new scheme for millimeter-wave wireless beam-steering using NxN patch-antennas with meandering-gaps on an electro-optic (EO) modulator is proposed for high-speed radio-over-fiber systems. The wireless receiving beam can be steered by controlling interaction between millimeter-wave and lightwave electric fields in EO modulation using meandering-gaps. Analysis and experimental demonstration of the proposed device for 40GHz millimeter-wave bands are reported. A 5×5 antenna array is designed for 0±30 degrees wireless steerable beams. 5 and 25 variations of wireless beam-steering can be obtained for 1-D in xz- or yz-planes and 2-D in xyz-space, respectively.
