Abstract
A novel compact tri-band band-pass filter (BPF) with transversal signal interaction concepts, based on composite right/left-handed transmission lines (CRLH-TLs) resonator and parallel stepped impedance resonator (SIR), is presented. The main path is based on a dual-mode CRLH-TL resonator, which exhibits the first two passbands. The secondary path is a SIR, which contributes to the third passband and generates another transmission zero between the first and second passbands simultaneously. The proposed filter has been simulated, fabricated and measured. Both the simulated and measured results show that the filter has a high selectivity with a compact size as small as 0.18λg×0.12λg.
