| 摘 要： | 短路针加载微带贴片天线具有较低的谐振频率,特别适用于低频便携式通信设备(如手机)中.与短路针加载矩形和圆形贴片天线相比,短路针加载三角形贴片天线具有更低的谐振频率.本文基于腔模理论,利用未加载三角形贴片天线的静态模,提出了短路针加载三角形贴片天线的理论分析方法,给出了天线谐振频率、输入阻抗及反射损耗的计算公式.数值计算与实测结果相吻合,表明这种分析方法是有效的.

| Abstract: | Microstrip patch antenna with a shorting pin has a lower resonant frequency,so it especially suits to low frequency portable communication equipments(such as handsets).Compared to rectangular and circular patch antenna loaded with a shorting pin,triangular patch antenna loaded with a shorting pin has lower resonant frequency.Based on the cavity model theory,this paper used the static mode of the unloaded triangular patch antenna to propose the analytical method of triangular patch antenna loaded with a shorting pin,and the calculation formulas of resonant frequency、input impedance and reflective loss for this kind of antennas are given.The numerical calculations agree with the measured results very well,verifying that this analytical method is valid. |

| Keywords: | microstrip patch antennas cavity model theory resonant frequency input impedance return loss |
