梯形双陷波超宽带平面单极子天线的设计与分析
Design and Analysis of Trapezoidal Double Band-Notched Ultrawideband Planar Monopole Antenna
【摘要】 设计一种梯形双陷波超宽带平面单极子天线,并分析改变C形缝隙陷波结构半径和L形缝隙对天线性能的影响.天线由梯形组合结构辐射单元、共面波导馈线、地板和同轴接头构成.结果表明,当设计的天线工作频段为2.9~11.2GHz,陷波频段为3.28~3.79GHz和4.82~6.08GHz时,双陷波与辐射效果良好,可降低各无线通信系统间频段交叉重叠导致的相互干扰.
【Abstract】 The author designed a trapezoidal double band-notched ultrawideband planar monopole antenna,and the influence of changing the radius of C-shaped gap band-notched structure and L-shaped gap on the antenna performance was analyzed.The antenna consisted of trapezoidal composite structure radiation unit,coplanar waveguide feeder,floor and coaxial joint.The results show that the working frequency range of the designed antenna is 2.9—11.2 GHz,the frequency range of the band-notch is 3.28—3.79 GHz and 4.82—6.08 GHz,double band-notched wave and radiation effect are good,which can reduce the mutual interference caused by cross-overlapping of frequency bands among wireless communication systems.
