研究了短路柱对微带圆盘天线谐振频率的影响。首先，给出了带有短路柱的微带圆盘天线谐振频率的解析解。然后将该解专门用于偶数和奇数激励的特殊情况。这些激发进一步加深了对短柱尺寸和位置对共振模式影响的理解。结果与实验结果吻合较好，表明短路柱的位置可以用来控制微带圆盘天线的谐振频率和极化，或者用来消除微带圆盘天线中不需要的模式。这些特性为微带圆盘天线的电子控制提供了一种手段。
This study investigates the resonant frequency of microstrip disk antennas affected by a shorting post. Initially an analytic solution for the resonant frequencies of a microstrip disk antenna with a shorting post is presented. The solution is then specialized to the special cases of even and odd excitation. These excitations further the understanding of the shorting-post size and location effects on the resonant modes. The results agree well with experimental results and indicate that the location of the shorting post may be used to control the resonant frequency and polarizations, or to cancel the unwanted modes of a microstrip disk antenna. These properties provide a means for the electronic control of microstrip disk antennas.
