Abstract

A novel compact broadband microstrip bandpass filter is proposed and developed on the basis of the frequency-distributed coupling behavior of the parallel-coupled microstrip line (PCML) and the multimode resonance of the stepped-impedance line resonator. Comprehensive investigation in this work is dedicated to a physical insight into its operating mechanism and theoretical characterization of its broadband filtering performance through the use of its complete equivalent circuit network. Finally, such a microstrip filter is designed, fabricated and measured, providing an excellent verification of its attractive features such as multiple transmission poles, broad passband and compact size.
