A Compact Dual-Band Quasi-Elliptic Filter Employing Meander-Line- and CRLH-Based SIW Triplets
Electromagnetic ScienceA compact dual-band quasi-elliptic filter with high selectivity is developed and investigated in this communication. It employs two hybrid-structure substrate integrated waveguide (SIW) triplets, which show completely inverse transfer responses under the

A DUAL-BAND BANDPASS FILTER WITH A TUNABLE PASSBAND
Progress In Electromagnetics Research C, 2013 In this paper, a novel dual-band bandpass fllter with a tunable passband is proposed. Based on two quarter-wavelength resonators and one half-wavelength resonator, dual-band character is designed by introducing two independent coupling paths. The fllter structure is designed and can be divided into two parts.

Compact Dual-Mode Triple-Band Bandpass Filter [PDF]
Journal of Electromagnetic Engineering and ScienceA dual-mode bandpass filter that allows for triple-band operation is proposed in this letter. The proposed filter uses a square patch as a resonator. A cross slot is located inside the patch, a pair of slits is applied to the edge of the patch, and a ...
