Corrugated substrate integrated waveguide with dual band non-Bragg resonance

Summary form only given, as follows. A corrugated substrate integrated waveguide (SIW) with dual non-Bragg resonance frequencies is proposed. Two resonance frequencies at 4.8 GHz and 8 GHz are demonstrated. Theoretical calculation, simulation, and measurement results show good mutual agreement. This kind of non-Bragg resonance is associated with the geometric configuration of the corrugated SIW.
