摘要

A small size and wide-band band pass filter with high performance for WiMAX applications is introduced. The filter is designed by utilizing one composite right left handed transmission line (CRLHTL) metamaterial cell and two gap lumped capacitors. The filter has a center frequency of 5.3 GHz and a 3dB bandwidth from 4.2 GHz to 6.4 GHz. A lower than 0.5 dB insertion loss within pass-band is achieved. A single transmission zero at 6.52 GHz is achieved to increase the selectivity of the proposed filter. The rejection band is extended to be up to 10 GHz. A comparison between circuit simulation, EM simulation and measured results is introduced with good consistency between them. The filter has a small size (26.8 x 16.5 mm(2)) which is smaller than recently reported wide band filters.
