Abstract
In this paper, an Ultra-wide-band (UWB) filter based on composite right/left handed transmission line (CRLH TL) is presented. The structure of the proposed band-pass filter is quite simple, of which the size is 0.5cm×1.5cm. Left-handed capacitor is obtained by couple of microstrip lines, and Left-handed inductance is obtained by the grounded stub. The simulated results indicate that the pass band of UWB filter is 3.4-11GHz, the insertion loss is less than 1 dB and the return loss is smaller than -12.5dB. The performance of UWB filter could meet the requirement of UWB communication systems.
