摘要：
In this paper, based on liquid crystal anisotropy characteristics, a kind of frequency reconfigurable comb substrate integrate waveguide slot leaky-wave antenna use liquid-crystal-based is proposed at Ku band. It adopt comb shape and defected ground structure to compose comb SIW's top and bottom. The slots are etched at top and bottom surface. The resonant point of propose antenna move from 15.85GHz to 14.37GHz, the tunable range is 1.5GHz by changing liquid crystal's permittivity. Return loss less than -30dB at resonant point and the maximum gain is 8.79dB. The bandwidth of proposed antenna is 1 GHz. All the results show the reconfigurable of proposed antenna is good.
