In this paper, a novel bandpass filter (BPF) using the composite right/left-handed transmission line (CRLH-TL) theory is presented.The composite right/left-handed TL with the high-pass characters of left-handed transmission line (LH-TL) and the low-pass characters of right-handed transmission line (RH-TL) are used to construct the bandpass filter.Using this theory,we design a bandpass filter which have an obvious band pass response with a wide passband range from 5.1to 12.9GHz and a low insertion loss of less than 3.1dB. The relative bandwidth is close to 110%. Simulation using ADS demonstrated the viability of the approach.

As one of the most important devices in the ultra-wideband (UWB) wireless communication system, UWB filter has received more and more attention with the rapid development of UWB wireless communication technology. In this paper, an ultra-wideband bandpass filter based on composite right/left handed transmission line (CRLH TL) is designed. The filter are simulated and optimized by the industry-standard simulation tool HFSS to examine the correctness and effectiveness of the design with the simulated scattering parameters S11 and S21.
