An apparatus is provided with a conductive bezel section and a conductive ground plane section forming a perimeter and being positioned opposite the conductive bezel section. The conductive ground plane section is separated from the conductive bezel section by a perimeter gap at the perimeter. A structural tank circuit is integrated with and connecting the conductive bezel section and the conductive ground plane section across the perimeter gap. Another implementation may include a structural capacitor or a structural inductor integrated with and connecting the conductive bezel section and the conductive ground plane section across the perimeter gap.

Structural tank integrated into an electronic device case

An electronic device case includes a conductive cap section and a conductive bezel section forming a perimeter outside the conductive cap section and separated from the conductive cap section by a bezel gap. A conductive ground plane section forms a perimeter and is positioned opposite the conductive cap section and the conductive bezel section. The conductive ground plane section is separated from the conductive bezel section by a perimeter gap. One or more components reside between the conductive cap section and the conductive ground plane section forming a resonant cavity including a ground plane resonant cavity portion between the one or more components and the conductive ground plane section and a substantially annular resonant cavity portion between the one or more components and the perimeters of the conductive bezel section and the conductive ground plane section.
