| 摘 要： | 该文设计了一种尺寸小,频带宽,结构简单的单极子陶瓷介质谐振器天线。在单极子天线周围加载一个环形的陶瓷介质谐振器,利用环形谐振器与单极子谐振频率之间耦合来展宽频带。利用仿真软件HFSS建立天线的模型,并对模型进行优化仿真,得到了最佳的天线设计参数,仿真得到的天线频带宽度为0.7～4.6GHz,相对带宽达到了153%,使用矢量网络分析仪对该天线进行测量,实测结果与仿真值基本吻合。

| Abstract: | This paper proposes a monopole ceramics dielectric resonator antenna which is characterized by small size,broad band,simple structure.A ring ceramics dielectric resonator is put around the monopole,and the frequency band is broadened by coupling the ring dielectric resonator with the monopole resonant frequency.The antenna model is established by using the HFSS simulation software,then the model is optimized and simulated and the optimal parameters of the antenna are obtained.The bandwidth of the antenna is from 0.7~4.6 GHz,relative bandwidth reaches to 153%.The antenna is measured by a vector network analyzer and the results and simulation values are basically coincide with each other. |
