新型SG-CRLH传输线结构的应用

Abstract

Abstract:

An ultra-wide band (UWB) dual-band bandpass filter is presented using a simplified general composite right/left-handed (SG-CRLH) structure. Each cutoff frequency is controllable by the values of elements. To enhance the spurious passband suppression, periodical complementary split-ring resonators (CSRRs) are introduced to form an extra transmission zero. Finally, an UWB dual-band bandpass filter (2.2～4.0GHz, 4.8～9.3GHz) is designed, fabricated and tested. The fractional bandwidths of the first and second passbands are 58% and 63.8%, respectively. The good agreement between measurement and simulation is observed.

Key words: simplified general composite right/left handed, general composite right/left handed, transmission line, complementary split-ring resonator, dual-band bandpass, filter, ultra-wide band
