Postwall-Slotline Stepped Impedance Resonator and Its Application to Bandpass Filter with Improved Upper Stopband
In this letter, a postwall-slotline stepped impedance resonator (PWS-SIR) is proposed and applied to a bandpass filter (BPF) with a wide stopband. The proposed PWS-SIR-BPF comprises three U-shaped PWS-SIRs and two microstrip-slot feeding transitions. A PWS has a much lower impendence which a convent...
