A bandpass filter based on novel CRLH TL transmission line structure

In this paper, a novel composite right/left handed transmission line (TL) structure is proposed. The CRLH TL has high-pass property at lower frequencies and low-pass property at higher frequencies, thus constructs a bandpass filter. Lumped or quasi-lumped microwave components are introduced to satisfy the necessity of the filter. Simulation using ADS and HFSS demonstrated the viability of the approach.
