摘要：

基于LTE，针对其工作频段（2.57~2.62 GHz），在矩形微带贴片天线的基础上，通过在贴片上开4个弯曲的缝隙和在高于
贴片1 mm处加载两个宽0.75 mm的方形环金属片而得到新型小型化加载开槽微带贴片天线。使用Ansoft公司的HFSS三维电
磁场软件对该天线进行建模仿真，并比较了开槽天线和新型加载开槽天线的尺寸、S 参数图、方向图以及驻波比。仿真结果表
明，该新型加载开槽微带贴片天线能在不降低天线各项性能的前提下，实现小型化，具有很好的实用价值。

Abstract:

For the working frequency of LTE（2.57~2.62 GHz）, based on the rectangular microstrip patch antenna, a novel
miniaturized loading slot microstrip patch antenna through opening four curved slits on the patch and loading two wide band 0.75 mm
square ring metal sheet at 1 mm above the patch has been obtained. And, the microstrip patch antenna has been modeled and
simulated by using the Ansoft's HFSS 3D electromagnetic analysis software. Then, the size, the S-parameter diagram, the pattern and
the VSWR of the slot antenna and the novel loading slot antenna have been compared. The simulation results show that the novel
loading slot microstrip patch antenna can achieve the miniaturization without compromising the performance of the antenna, and it's
has good practical value.

Key words: microstrip antenna, loading slot, miniaturization, LTE
