A CRLH TL Transmission Line Structure and its Application to Bandpass Filter Design

Article Preview

Abstract:

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.
