Abstract

A novel Ku‐band transition and power divider between rectangle waveguide (RWG) and substrate integrated waveguide (SIW) is proposed. This transition and power divider is realized by a radiating metal patch located on the backside of a middle dielectric substrate and a coupling aperture etched on the SIW's ground plane. The transition and power divider is studied both simulatively and experimentally. As reported, low insertion loss of not higher than 0.6 dB and good return loss of −15 dB may be achieved at the frequency range of 12.1–12.8 GHz. The method to increase the bandwidth is investigated. © 2009 Wiley Periodicals, Inc. Microwave Opt Technol Lett 52: 375–378, 2010; Published online in Wiley InterScience (www.interscience.wiley.com).
