A novel compact dual-band half-mode substrate integrated waveguide bandpass filter

Summary form only given, as follows. This paper presents a novel dual-band bandpass filter (BPF) using half-mode substrate integrated waveguide (HMSIW) technology for the first time. The proposed filter is at least six times smaller than its conventional substrate integrated waveguide (SIW) counterpart. A three-pole dual-band Chebyshev BPF with center frequencies of 1.05 GHz and 1.3 GHz is implemented on RT/Duroid 6010LM substrate. To our knowledge, this filter is the state-of-the-art in dual-band BPFs using SIW technology.
