Abstract
There is disclosed an electronic device comprising a front surface including a display screen and a non-metallic bezel surrounding the display screen, and a metallic rear surface. A cavity is defined between the rear surface and the bezel of the front surface along at least a portion of the bezel. The electronic device further comprises a conductive radiating element and a conductive ground plane. The conductive radiating element is mounted in or adjacent to the cavity so as to face the non-metallic bezel in a first direction towards the front surface, and to face the cavity in a second direction towards the rear surface. The conductive radiating element is connected to the conductive ground plane and is additionally connected to the metallic rear surface. The conductive radiating element is configured for excitation by an RF feed, and the cavity serves as a reflector to direct RF signals through the bezel.
