基于仿生学原理,以对称牛头形设计了一款小型超宽带双陷波功能微带天线。该天线包括带有“牛角”的对称牛头形的主体辐射单元,采用共面波导结构进行馈电。通过仿真及实验验证可以看出该天线在3.3~3.8GHz和5.0~5.5GHz具有良好的陷波特性,天线的驻波比从2.1GHz覆盖到了14.4GHz(VSWR<2),相对阻抗带宽超过了149%。
Based on the principle of bionics, a small ultra-wideband dual-notch microstrip antenna is designed with a symmetrical head shape. The antenna consists of a main body radiating element with a symmetrical bull-shape with a “horn”, fed by a coplanar waveguide structure. It can be seen through simulation and experimental verification that the antenna has good notch characteristics at 3.3-3.8GHz and 5.0-5.5GHz. The VSWR of the antenna is covered from 2.1GHz to 14.4GHz (VSWR <2), and the relative impedance bandwidth exceeds 149%.
