Abstract

In this paper, a filter for the ultra-wide band (UWB) ranging 3GHz ~ 10.5GHz has been designed by taking the advantage of the metamaterial Composite Right & Left-Handed Transmission-line (CRLH-TL) with a Shorted Open Gap Ring Resonator (SOGRR) structure and an inter-digital line. In order to bring the remarkable improvement in an attempt to reduce the total metamaterial cell size, only one cell of the SOGRR with the inter-digital line is taken. This metamaterial filter will be shown to have the size of 15mm×15mm, the fractional bandwidth over 100%, the insertion loss much less than 1dB, and an acceptable return loss.
