The frequency-dependent complex permittivity is determined for a printed circuit board laminate. For this purpose, measurements performed to an array of striplines are systematically processed. The methodology presents the advantage of employing lines embedded within the same laminate without requiring multiple prototypes. From the extracted data, a Debye model is implemented to yield a wideband representation of both, the relative permittivity and the loss tangent. Moreover, the line’s characteristic impedance is reconstructed and causal time-domain simulation results are achieved.

确定复介电常数因果模型的带状线宽度阵列方法
确定印刷电路板层压板的随频率变化的复介电常数。为此,系统地处理对带状线阵列执行的测量。该方法具有使用嵌入在同一层压板中的线而无需多个原型的优势。从提取的数据中,实施德拜模型以产生相对介电常数和损耗角正切的宽带表示。此外,重构了线路的特征阻抗,并获得了因果时域仿真结果。
