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。

The frequency response may also be controlled by a low voltage micro sized varicap, or a varactor diode, and instantiated as a tuned, resonant matching filter network residing with the antenna module.
