In this paper, a novel sextuple mode resonator (SMR) is proposed to design a compact ultra-wide dual-band bandpass filter (BPF) with high selectivity. An even- and odd-mode analysis method is employed to analyze the proposed SMR, and the SMR can excite six resonant modes simultaneously. In addition,...
