Design of two-layer substrate integrated waveguide slot array antenna

Based on the substrate integrated waveguide (SIW) technology, a two-layer slot array working at Ka band is designed by transferring the conventional waveguide resonant slot array antenna to the substrate integrated waveguide structure., which fed by standard metallic waveguide. The integration of the slotted-waveguide array with the feeding network is an important goal in the design process. Reduced size of the antenna can be obtained using multilayered substrates, the power divider can be integrated in different layers at the bottom of the slot array antenna by coupling inclined slots. with the characters of small, light weight, simple framework, it can be easy for produce.
