Abstract
An coupled antenna apparatus particularly well adapted for small form factor, metal encased applications that utilize satellite wireless links, e.g. GPS. Certain examples use electromagnetic feeding that includes one or more separate feed elements that are not galvanically connected to a radiator element of the antenna. Additionally, one radiator element of the antenna can be located on an outermost surface of a bezel of an electronic device, for example a wrist-wearable device. A low capacitance transient voltage suppressor diode is housed within an electronic device and electrically coupled to such an outer radiator element.
Claims19
A coupled antenna apparatus, comprising:
- a bezel for a wearable device, said bezel including an outer radiator element, wherein the bezel has an outer surface for use as an outer surface of the wearable device and an inner surface,
- a low capacitance transient voltage suppressor electrically coupled to the outer radiator element, and
- at least one additional radiator element electrically isolated from, but mechanically connected to the inner surface of the bezel, and
- at least one feed element galvanically isolated from the outer radiator element,
- wherein the outer radiator element includes at least a portion of the outer surface.
A wrist-wearable electronic device comprising:
- an outer housing including a bezel and a body,
- at least one feed element galvanically isolated from an outer radiator element,
- wherein the bezel includes the outer radiator element,
- a low capacitance transient voltage suppressor electrically coupled to the outer radiator element, and
- at least one additional radiator element within the outer housing electrically isolated from, but mechanically connected to the inner surface of the bezel and electromagnetically connected to the outer radiator element,
- wherein the bezel has an outer surface for use as an outer surface of the outer housing and an inner surface, wherein the outer radiator element includes at least a portion of the outer surface.
