Electronic device with conductive housing and near field antenna
First Claim
1. An electronic device, comprising:
- a housing having a conductive housing surface;
a dielectric-filled region in the conductive housing surface; and
a substantially planar antenna that at least partly overlaps the dielectric-filled region, wherein the conductive housing surface comprises a metal surface and a display having an exterior surface, wherein the metal surface surrounds the display, wherein the dielectric-filled region is formed in the metal surface, and wherein a portion of the planar antenna lies on the exterior surface of the display.

Abstract
An electronic device such as a computer monitor is provided that has an antenna that supports near field communications. The electronic device may have a housing with conductive housing surfaces. A display may be mounted in the housing. The conductive housing surfaces may contain a dielectric-filled hole. The antenna may have a substrate and one or more loops of conductive traces. The loops may exhibit mirror symmetry. The loops may overlap the display and the conductive housing surface. The loops may surround an inner loop-free portion of the antenna. The loop-free portion of the antenna may overlap the hole. Ferrite layers may be interposed between the loops of the antenna that overlap the display and the loops of the antenna that overlap the conductive housing.
