Description

Negative group delay characteristics can be used to signal processing devices such as equalizer for compensation of the group delay of systems, and pulse compression circuit of radar systems. In this paper, to clarify negative group delay characteristics achieved by planar structure on an IC chip, we designed the Folded-Stepped Impedance Resonator (F-SIR) structure on printed circuit board (PCB), which has the symmetrical electric-wall at the guide center driven by differential-mode. The group delay characteristics were discussed experimentally and with FDTD modeling. It was demonstrated that the negative group delay is achieved at anti-resonant frequencies.
