Four port substrate integrated waveguide (SIW) directional couplers for Ku and Ka bands are conceived. Initial design directional coupler -3 db follow substrate integrated waveguide selection and aperture coupling theory as known from standard air-filled waveguide components. The simulation results using HFSS and CST software demonstrate that this design approach is satisfactory for many applications. Tapered microstrip ports are used as interfaces to the SIW couplers. Performances of design models of -3dB 90° SIW couplers described in this paper are analyzed.
