Antenna for device having conducting casing

摘要

The invention concerns an electronic device for personal use and a coupled antenna apparatus for such a device, comprising a top cover and a housing with an opposing back cover configured to form a closed space between said top and back cover that is adapted to receive electronic circuitry and a display unit. A bezel made of a conductive material is forming a rim on top of said housing and is interfacing with the top cover. According to the invention, an elongate strip of a conductive material deposited on a first side of an elongate antenna feed element and is forming a first radiating element and a second elongate strip of a conductive material deposited on a second side of the antenna feed element is forming a second radiating element, whereby the first and second radiating elements are positioned in proximity against the bezel at at least one inner wall portion of the bezel that extends in a direction between the first and second radiating elements and the display unit. The first and second radiating elements are functionally coupled to said bezel to form an antenna system of said electronic device.
