Dual band bandpass filters with full band reflectionless response and enhanced upper stopband suppression
Abstract This paper presents a novel dual-band bandpass filter (BPF) with two-port all-frequency reflectionless characteristics and enhanced upper-band suppression. The design integrates a square ring resonator (SRR) and advanced coupled lines (CLs), incorporating complementary absorptive branches t...
