Abstract One kind of novel microwave planar power dividing/combining network based on substrate‐integrated waveguide (SIW) directional couplers is proposed and investigated. The design strategies of the broadside‐coupling SIW directional coupler are introduced, the series connection of several directional couplers with different coupling ratio then result in a multiway power dividing/combining network. One three‐way power dividing/combining network is designed and fabricated to demonstrate the validity of the proposed work, high isolation among the ports is observed. © 2009 Wiley Periodicals, Inc.
