Claim:
1. An apparatus comprising: a substrate comprising first and second ground plates; a substrate integrated waveguide (SIW) antenna element located along an edge of the substrate; a feed line configured to at least one of: provide signals to the antenna element and receive signals from the antenna element; and a feed via connected to the feed line, wherein the feed via is configured to transfer a signal from the feed line to a bottom one of the first and second ground plates, wherein the antenna element comprises a waveguide between the first and second ground plates that is enclosed by vias through the substrate, the waveguide including one open edge along the edge of the substrate, and wherein sidewalls of the waveguide are formed by multiple lines of the vias that penetrate the first and second ground plates and enclose the waveguide except for the one open edge.
