| 摘 要： | 该文设计了一款可展宽频带的微带贴片天线。通过贴片切角改变电流路径展宽频带，贴片中心切去“梅花”增加电流路径来减小贴片尺寸。采用基于有限元算法的高频电磁仿真软件对该天线进行了仿真，仿真结果显示其阻抗带宽达到15％，满足现代许多无线电通信的要求。测量结果验证了该方法的可行性和正确性。

| Abstract: | This paper designs a wideband microstrip patch antenna. The bandwidth is expanded by cutting two fans in the comer of the patch antenna to change the current patch. The size of the patch is reduced by cutting a ＂plum＂ in the center of the patch antenna to expand the current path. The antenna is simulated using high-frequency electromagnetic simulation software based on finite element（FE） method. The simulation results show that the impedance bandwidth roaches 15%. It meets the requirements of modern radio communication. The measurement demonstrates the validity and correctness of the design. |
