This letter presents a novel class of compact dual-mode bandpass filters based on half-mode substrate-integrated waveguide (HMSIW) cavities. By using both TE 102 and TE 301 modes of the HMSIW rectangular cavity as resonant modes and TE 101 mode as nonresonating mode, a novel HMSIW doublet with two p...
