Abstract
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.
