Compared to rectangular and circular patch antenna loaded with a shorting pin, triangular patch antenna loaded with a shorting pin has lower resonant frequency.

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。

Using this method, a rectangular microstrip patch antenna loaded with a shorting pin is designed which operated at mobile communication frequency.

该优化设计方法共分两步进行，首先，对天线的频率特性进行优化，然后在此基础上对天线的阻抗特性进行优化。
