With the development of 5G technology, accurate measurement complex permittivity a printed circuit board (PCB) in wide frequency range is crucial for design high-frequency circuits. In this paper, microwave device and method based on double-sided parallel-strip line (DSPSL) resonator have been developed to measure typical PCBs vertical direction. The includes DSPSL resonator, coupling probe, pressure monitor, Farran C4209 vector network analyzer (100 K 9 GHz), FEV-10-PR-0006 multiplier...
