DOI: 10.1002/mop.32831

Abstract: In this paper, a thirty‐second‐mode circular substrate integrated waveguide resonator (TMCSIWR) is firstly investigated, which well retains the fundamental mode and high‐order modes (TM0n0 modes) in circular SIW resonator (CSIWR) for stable transmission. Considering miniaturization,… read more here.
