Design Substrate Integrated Waveguide Slot Array Antenna At X-Band

Substrate integrated waveguide (SIW) is a rectangular dielectric-filled waveguide, which is synthesized in a planar substrate with arrays of metallic vias to realize bilateral side walls and its transitions with planar structures. These vias act as walls of the waveguide supporting current flow, thu...
