| 摘 要： | 文章介绍了一种新型宽带双频全向单极天线。在正方形单极天线贴片的基础上寄生一块矩形贴片的方法达到双频工作的效果,且在每个谐振点都具有宽带特性;同时,为了克服单极天线在高频段却很难达到全向或者接近全向辐射模式的缺点,采用一种简单的阶梯型结构,在高频段提供良好的全向辐射特性。

| Abstract: | A novel broad-band omnidirectional monopole antenna with dual-frequency is presented.The proposed antenna has dual-frequency and broad bandwidth characteristics at both resonant frequencies,which consist of two connected elements.In order to overcome the drawback of the monopole antenna that it can not achieve omnidirectional or near-omnidirectional radiation pattern in higher operating frequencies,a step-shaped monopole antenna is designed to improve omnidirectional radiation. |
