Abstract: In this article, a simple compact broadband right-angle transition between substrate integrated waveguide (SIW) and rectangular waveguide (RWG) working at Ka-band is proposed. Three coupling slots etched on the interface are developed to couple the electromagnetic field from SIW to RWG. A metallic via is introduced into the end slot to enhance the inductance and all the slots are developed in different dimensions for multi-resonance. By proper optimizing, three resonances are obtained which broadens the impedance matching effectively. All details of the transition are designed on the SIW part for the purpose of simple and compact. Two back-to-back prototypes working at Ka-band are designed, fabricated and measured. The measured results show that the mean value of insertion loss for a single transition is about 0.51 dB and the return loss is better than 15 dB over the full Ka-band. The proposed right-angle transition has advantages of simple assembly, compact size and broadband characteristics and it can be a good candidate for millimeter-wave applications.
