Abstract
The disclosed embodiments include a housing of a handheld mobile device. The housing includes a ceramic layer forming a continuous outermost surface of the handheld mobile device, and an antenna layer adjacent to the ceramic layer. The antenna layer including conductive elements formed from a metal injection molded substrate, and an antenna break formed of non-conductive material electrically separating the conductive elements to collectively form an antenna of the handheld mobile device that is hidden by the ceramic layer from an exterior view of the handheld mobile device.
Claims20
A housing of a handheld mobile device, the housing comprising:
- a ceramic layer forming a continuous outermost surface of the handheld mobile device;
- and
- an antenna layer underlying the ceramic layer, the antenna layer including:
- a plurality of conductive elements formed from a metal injection molded (MIM) substrate;
- and
- an antenna break formed of non-conductive material electrically separating the plurality of conductive elements to collectively form an antenna of the handheld mobile device that is at least partially hidden by the ceramic layer from an exterior view of the handheld mobile device.
A smartphone device comprising:
- a case forming a housing of the smartphone device, the case including:
- a continuous outermost surface of the case;
- and
- an antenna structure hidden from an exterior view of the handheld mobile device by the continuous outermost surface of the smartphone device, the antenna structure including:
- a plurality of conductive elements formed of a metal injection molded (MIM) substrate;
- and
- an antenna break formed of non-conductive material separating the plurality of conductive elements to collectively form the antenna of the handheld mobile device.
A antenna structure comprising:
- a plurality of conductive elements formed of metal injection molded titanium and separated by a non-conductive material;
- a titanium oxide coating on a first side of the plurality of conductive elements;
- and
- an insulating coating on a second side of the plurality of conductive elements opposite the first side such that the plurality of conductive elements are electrically insulated from each other by the non-conductive material, the titanium oxide coating, and the insulating coating.
