Abstract

In this paper, a narrow bandwidth dual-band (DB) band-pass filter (BPR) with λ_g/2 open stubs using composite right/left-handed (CRLH) meta-material transmission lines is presented. A conventional narrow BPF with λ_g/2 open stubs is first designed using series λ_g/2 open stubs and λ_g/4 transmission lines. Then, a DB filter can then be easily implemented by replacing the microstrip lines with the CRLH transmission line unit-cells. The DB BPF using the CRLH transmission line unit-cell is experimentally demonstrated at dual operating frequencies of 5.8 GHz and 10.02 GHz. The experimental results are in a good agreement with the simulation results. The DB BPF shows 11 % and 13 % pass bandwidth at the center frequencies of 5.8 GHz and 10.02 GHz, respectively.
