| 摘 要： | 设计一种双Z型缝隙结构的双频微带贴片天线,通过加载缝隙改变贴片表面电流路径的方法来实现天线的双频带,并利用电磁仿真软件HFSS 13.0对天线进行仿真分析.结果表明,当回波损耗小于-10.0 dB时,天线工作频段分别为2.44～2.56 GHz和4.92～ 5.08 GHz,且天线的相对带宽分别为4.8％和3.2％.与普通微带天线相比,该天线的带宽有很大的提高,天线的整体辐射性能良好,且结构简单易实现,所设计的双频微带天线可用于无线通信系统中.

| Abstract: | A novel Z-shaped mierostrip antenna is investigated in this paper. The antenna can realize the function of com- pact and multi-frequency by changing the patch surface current path. Numerical simulation is performed for the antenna with the software HFSS 13.0. The simulation results show that the operation frequencies of this antenna are 2.44 ～ 2. 56GHz and 4.92 ～ 5.08GHz with return loss less than - 10.0dB, and the relative bandwidths of the antenna are 4.8% and 3.2%. Moreover, compared with the conventional mierostrip antenna, the antenna has higher bandwidth and good uni- tary radiation and simple configuration. Therefore, this antenna can be used in RF communication as a dual-frequency mi- erostrip antenna. |
