Design and Optimization of a Microstrip Bandpass Filter for Ultra Wideband (UWB) Wireless Communication

S. Seghier, N. Benabdallah, N. Benahmed, and K. Nouri
Abstract—A new technique is developed for designing a composite microstrip bandpass filter (BPF) with a -3dB fractional bandwidth of more than 100%. The BPF is suitable for ultra-wideband (UWB) wireless communications. The design utilizes embedding individually designed high-pass structures and low-pass filters (LPF) into each other, followed by an optimization for tuning in-band performance. The stepped-impedance LPF is employed to attenuate the upper stop-band and quarter-wave short-circuited stubs are used to realize the lower stop-band. The filter had a good performance, including an ultra-wideband bandpass (3-10 GHz), a small size, low insertion loss, return loss better than 18 dB from 3.8 GHz to 9.3 GHz and sharp rejection. The filter also demonstrated an UWB reject band from 11.4 GHz to more than 20 GHz at -20dB.

Index Terms—Bandpass filters, microstrip lines, microstrip filters, ultra-wideband, wideband filters.
