中文说明：矩形微带天线尺寸计算：输入相应的输入参数工作频率，介质板厚度，介电常数就可以根据经验公式得出矩形贴片天线的尺寸，另外还包含一个微带线宽度计算，输入特征阻抗值，根据刚才输入的介质板厚度和介电常数，计算出相应的宽度。
English Description：
Rectangular microstrip antenna size calculation: input the corresponding input parameters, working frequency, dielectric plate thickness and dielectric constant, then the rectangular patch antenna size can be obtained according to the empirical formula. In addition, it also includes a microstrip line width calculation, input the characteristic impedance value, and calculate the corresponding width according to the dielectric plate thickness and dielectric constant just input.
