A substrate integrated waveguide (SIW) slot antenna may include a substrate that may have a first substrate portion with a first permittivity less than unity and a second substrate portion with a second permittivity. The substrate may include a top surface and a bottom surface. The exemplary SIW slot antenna may further include a first conductive layer disposed on the top surface, a second conductive layer disposed on the bottom surface, a transverse slot on the first conducting layer, waveguide sidewalls that may include a plurality of spaced-apart metal-lined vias traversing the substrate, and a microstrip feed line on the first conducting layer.
