The results show that too high or too low dielectric constant of the substrate, too thick or too thin of the substrate size can affect the antenna performance obviously.
研究表明，基质介电常数过高或过低、基质尺寸过厚或过薄，都会使天线的性能显著下降。

Based on the measured input impedance characteristics or the resonance parameters of a micro-strip antenna the dielectric constant can be obtained with the help of a computer.
借助计算机程序，可由微带天线的输入阻抗特性或谐振参数直接求出介电常数。
