Abstract
According to one embodiment, a waveguide antenna includes a top plane made of electrically conductive material, a bottom plane made of electrically conductive material, a first feed member coupled to the top plane and the bottom plane through a first via, the first feed member to be electrically coupled a transceiver of an electronic device, and an array of vias disposed surrounding the first via. The array of vias coupling the top plane and the bottom plane to form a cavity between the top plane and the bottom plane. When an electrical signal is provided to the first feed member, the first feed member excites a space within the cavity between the top plane and the bottom plane.
