Magneto-Dielectric Substrate Effect on Bandpass li-Circuit Negative Group Delay(NGD) Performance

2020 International Conference on Smart Electronics and Communication (ICOSEC), 2020
This paper investigates the influence of magneto-dielectric (MD) substrate permeability on the bandpass (BP) Negative Group Delay (NGD) performance. The present BP NGD analysis is based on microstrip li topology. The circuit proof of concept is designed with a coupled line (CL) having a physical 40-cm length and l-mm space.
