摘要
Abstract
Based on the in-phase reflection characteristic,the high impedance surfaces are placed on the edge region of Ar-chimedean spiral antenna backed cavity to improve the antenna gain and realize low-profile design. The results of simulation show that the stability of gain is enhanced significantly compared with traditional cavity-backed spiral antenna. The VSWR is smaller than 2 in the work frequency from 3 GHz to 12 GHz,so the impedance matching is proper,and the radiation pattern re-mains stable. The axial ratio is less than 3 dB when in the bandwidth of 7.8 GHz,so that circularly polarized wave can be achieved.关键词
