Abstract
A substrate integrated waveguide having multiple substrate comprises a first substrate and a second substrate stacked with the first substrate, wherein metal layers are formed on opposite sides of the first substrate and opposite sides of the second substrate, a plurality of metal holes are formed between two metal layers of the same substrate to limit transmission paths of electromagnetic waves transmitted in the substrate, and areas having no metal therein are formed between the first and second substrates so that the electromagnetic waves could be transmitted between the first and second substrates thereby.
