Abstract

A compact ultra-wideband (UWB) bandpass filter (BPF) based on transversal signal-interaction concepts is proposed in this letter. Two transmission paths with a wideband double-sided parallel-strip line (DSPSL) 180° swap and a 3λ/4 transmission line are used to transmit signal from Port 1 to Port 2. Two λ/4 shorted lines are introduced to improve the passband transmission characteristic. Two transmission zeros and good harmonic suppression can be achieved in the whole band. One prototype with 3-dB fractional bandwidth of 108% (1.35-4.6 GHz) is fabricated for demonstration, and good agreement is observed between simulated and measured performances. © 2013 IEEE.
