人工表面等离激元馈电的宽带低旁瓣全角度波束扫描天线
A Wideband Full-Angle SSPP-Fed Beam-Scanning Antenna with Low SLL
摘要
Abstract
A wideband and wide-angle beam-scanning antenna with low sidelobe levels(SLL)fed by spoof surface plasmon polaritons(SSPP)is designed.The SSPP feeding lines are adopted to excite the oval radiating patch array in the fast wave zone,whereas its low loss transmission in the slow wave zone is used to excite the spoof plasmonic antipodal Vivaldi antenna(AVA),realizing the beam scanning angle of 180° within 4~12 GHz(a relative band-width of 100%).And by arranging the oval radiating patches in a tapered way,the SLL during leaky-wave radia-tion is effectively reduced.The simulation results show that the SLL of the designed full-angle beam-scanning an-tenna is below-10 dB within the 4~12 GHz frequency band.Such antenna has considerable potential in applica-tion under condition of radar detection and target tracking.关键词
