This paper explores an original research work on multiband metallized-permittivity measurement method for copper-clad substrates based on bandpass (BP) negative group delay (NGD) ring circuit. The multiband permittivity extraction formula from NGD center frequency harmonics is established from S-parameter model. The BP-NGD function specifications of are defined. The BP-NGD ring resonator (RR) proof-of-concept (PoC) consists of linearly coupled loops implemented in microstrip technology.
