摘要
基于微带贴片天线在无线引信中的应用,设计了一种中心频率为7.2 GHz的同轴馈电圆形微带天线,该天线介质基片相对介电常数为εr=4.4,回波损耗小于-20 d B,天线增益大于5 d B。根据微带天线原理,通过HFSS软件设计的天线,实验结果表明:天线谐振频率、回波损耗等性能参数符合设计要求。
A coaxial feed circular microstrip antenna with central frequency of 7.2 GHz was designed based on the application of microstrip patch antenna in the wireless fuze. The antenna dielectric substrate′s relative dielectric constant is εr=4.4, its return loss is less than 20 dB and the antenna gain is greater than 5 dB. According to the principle of microstrip antenna, the antenna designed with HFSS software was tested. The results show that the antenna resonant frequency,return loss and other performance parameters can meet the design requirements.
