| 摘 要： | 文章提出了一种实现三角形微带天线宽频工作的新方法。通过添加一对与三角形中心线对称的L形缝隙，天线可以实现双频工作。改变L形缝隙的位置和尺寸，天线可以实现双频比在1．03—1．35范围内的调节，利用Ansoft仿真软件HFSS进行优化，当频率比为1．03时天线可以实现宽频工作。制作了实际的宽带天线，测量结果与仿真结果吻合，实测天线的相对工作带宽（VSWR〈2）为5．39％，是普通三角形微带天线的4．5倍，证明了所提出方法的有效性。

| Abstract: | A novel wideband microstrip triangular patch antenna is proposed.The dual-band operation is realized by loading a pair of L-shaped slots,and a variation range of 1.03 to 1.05 for the frequency ratio between two resonant frequencies can be achieved by varying the length of the L-shaped slots and the distance between them.By setting the frequency ratio to 1.03,wideband operation of the triangular microstrip antenna near its fundamental resonant mode can be realized through the optimization tool of Ansoft HFSS... |
