Abstract
An illustrative example electronic device includes a substrate integrated wave guide (SIW) comprising a substrate and a plurality of conductive members in the substrate. An antenna member is situated at least partially in the substrate in a vicinity of at least some of the plurality of conductive members. A signal generator has a conductive output electrically coupled with the antenna member. The antenna member radiates a signal into the SIW based on operation of the signal generator.
