Abstract

In this work, coplanar waveguide was fabricated on flexible PES substrate, and their RF loss characteristics were extracted using transmission line theory. Concretely, several Q-factors of the coplanar waveguides were extracted using transmission line theory. Firstly, Q_L was characterized using the equivalent RLGC circuit. According to measured result, the Q_L was 25.7 at 49.8 GHz. Q-factor was also extracted from a resonant tank built using a one-quarter of a wavelength long line at the resonance frequency f₀. According to the measured result, the Q-factor measured from one port open stub resonant circuit was 38.3 at a resonance frequency of 49.8 GHz, which was much higher than the open stub on silicon substrate.
