摘　　要：针对无线电引信天线提高增益的同时难以保留较大探测角的问题,提出了无线电引信圆形微带天线辐射性能改善方法。该方法设计了可组成环形的新型磁负超材料结构单元,并蚀刻在圆形微带天线主辐射边两侧以提升天线辐射性能。仿真结果表明,加载超材料单元后天线增益提升了0.911 dB,天线E面半功率波束宽度增加了3°,天线H面半功率波束宽度减少了12°,并发现辐射的后向波电平大幅度降低,较好地满足无线电引信对天线的要求。Aiming at the problem that the antenna of radio fuze had higher gain and it was difficult to retain large detection angle at the same time,a method to improve the radiation performance of the circular microstrip antenna of radio fuze was proposed.In this method,the new type of ring-shaped negative-μmetamaterials structure unit was designed and etched on both sides of the main radiation side of the circular microstrip antenna to improve the radiation performance.The simulation results showed that the gain increased by 0.911 dB,the HPBW of E-plane increased by 3°,the HPBW of H-plane decreased by 12°,and the radiated back-wave level decreased by a large margin,which satisfied the requirements of radio fuze for antenna.
