A tapered small‐size EBG microstrip bandstop filter design with triple EBG structures

A novel tapered small-size electromagnetic band-gap (S- EBG) microstrip filter structure is proposed and implemented. This struc- ture is comprised of a main 1D microstrip EBG structure and two auxiliary EBG structures arranged in a compact configuration and Chebyshev distri- bution is adopted to eliminate ripples in the passband. It exhibits an ultra- wide stopband with high attenuation and excellent transmission in the pass- band, yet the circuit area remains small. © 2005 Wiley Periodicals, Inc.
