Abstract

A miniaturized ultra-wideband (UWB) bandpass filter (BPF) with U-slot etched around the metallic via in the ground is proposed based on a simplified composite right/left-handed transmission line (SCRLH TL) structure. The U-slot etched in the ground makes it feasible to reduce the overall size. A demonstration of FCC standard UWB bandpass filter (BPF) is designed, fabricated and measured. Very good agreement is shown between measurement and simulation.
