Broadband Bandstop Filter Using Periodic Fractal Electromagnetic Bandgap Structures

A broadband, bandstop filter with sharp cut-off frequencies is presented, using novel designs of periodic fractal electromagnetic bandgap (EBG) structures. The sharp selective bandstop filter is constructed by cascading two EBG dual-ear cells with good...
With the rapid development of modern communications, efficient utilization of more and more frequency channels is necessary. Microwave filters have been widely used in modern communication systems. In recent years, more novel filters, using new technologies, continue to challenge traditional radio frequency (RF) components with ever more stringent requirements,...
