Designing of Bandpass Filter using CRLH Transmission Line and Floating slot
نویسندگان
چکیده
This paper presents construction of a composite right/left-handed (CRLH) transmission line (TL) based bandpass filter using microstrip parallel coupled lines and hairpin lines. For getting high coupling in comparison to conventional edge coupled microstrip line, the floating slot on the ground plane is used. Two configuration named as SOS (short-open-short) the OSO (open-short-open) model are studied for realization of band pass filter. The floating ground equalizes the even and odd mode phase velocities and solves the difficulties arised in the fabrication process as it relaxes the required physical dimensions like coupled gaps between lines. The Hairpin structure makes the structure more compact in size. Keywords—Composite right/left handed transmission line(CRLH), Floating slot, Open-short-open, Short-openshort, Bandpass filter, Hairpin structure.

Tunable Bandpass Filter with Varactors Based on the CRLH-TL Metamaterial Structure
This paper presents a tunable bandpass filter based on the varactor-loaded composite rightand left-handed transmission line (CRLH-TL). The proposed filter is composed of one CRLH-TL unit cell, which corresponds to the third-order bandpass filter. The tunable bandpass filter is designed using only lumped-elements. The use of lumped elements saves space and lowers the fabrication cost. The size o...
