Complementary metamaterial transmission line for monoband and dual-band bandpass filters application

Abstract

A novel composite right-/left-handed transmission line (CRLH TL) and its equivalent circuit model are proposed based on cascaded complementary single split ring resonator (CCSSRR). It features an intrinsically balanced wider band and an additional transmission zero above the right-handed band relative to CRLH TL using complementary single split ring resonator and complementary split ring resonators. Moreover, two single negative (SN) metamaterial (MTM) TLs constructed by using complementary electric inductive-capacitive resonator on the conductor strip and on the ground, respectively, are researched. Both SN MTM TLs exhibit electric resonance above the fundamental magnetic resonance. For application, a monoband (MB) bandpass filter (BPF) covered WLAN band, and a dual-band (DB) BPF covered satellite DMB band and WiMAX band are designed, fabricated, and measured. The SN MTM TLs are adopted for the sake of deep and wide out-of-band suppression while CRLH MTM TLs using square-shaped and Sierpinski-shaped CCSSRR are critical factors of the MB and DB behavior.

Novel configuration of ultra‐wide band uni‐planar configuration of complementary split ring resonator composite right/left‐handed based band pass filter with sharp roll off and good stopband attenuation

“…Recently, a Uni‐Planar CSRR version, which is etched in the top metal plane has been suggested as a simpler microstrip structure in fabrication and lower radiation losses and more compatible in packaging alone with the same functionality of CSRR. Both of the structures are widely used for various filters designs as 31‐37 and other microwave components as 38‐40 …”

“…Numerous antenna designers have spurred metamaterial inspired structures for improving the performance of the antenna. Complementary split ring resonator (CSRR) based metamaterial has been synthesized to compose microwave components such as power divider, branch line coupler, and band pass filters . CSRR based artificial material performs image rejection in RF down‐converter, reduce side lobe level, gain improvement, good impedance matching, and multiband antenna design .…”
