摘要
采用由微带线与射频信号源、频谱分析仪构成的简易实验装置,可准确测量出FR4介质板的相对电容率,降低了射频电路或微带天线设计实验的成本.
A simple experimental device, which consisted of microstrip line, a RF signal source, and a spectrum analyzer, can accurately measure the relative permittivity of FR4, and reduce the costs of the experiments of RF circuits or microstrip antenna design.
