可调频矩形贴片天线的研究

On Study of a Tunable Rectangular Patch Antenna

本文首次采用有限元法对有调谐销钉的可调频薄基片矩形贴片微带天线的谐振频率和输入阻抗进行了计算，谐振频率的计算结果与实验结果符合很好．该方法原则上适合于任意数目调谐销钉置于任意位置的情形．可能会是处理带调谐销钉的最有效的方法．

Finite Element Method (FEM) was first applied to calculate the impedance and resonant frequency of a thin substrate rectangular antenna with tuning post. The results of the resonant frequency are in agreement with the experimental data very well. In principle, this method is applicable to the antenna with many tuning posts in arbitrary places. Perhaps this method is the best one for analyzing the rectangular antenna with tuning posts.
