Abstract

In this paper metmaterial narrow band bandpass filter is designed and tested. The filter designed has the following properties, resonant frequency at 900MHz for mobile communications, bandwidth equal to 80MHz, insertion loss lower than -1.3dB, with in-band return loss lower than -16dB, and a wide stopband. The total filter size is about 2cm×2.4cm which is very compact compared to other metamaterial and conventional microstrip filters. This metmaterial narrow bandpass filter is designed based on composite right left handed (CRLH) Transmission line CL-loaded approach. The design steps, simulated and experimental results of the designed filter are presented
