Antenna structure for a wireless device with a ground plane shaped as a loop
First Claim
1. A wireless device including an antenna structure comprising:
- an antenna element;
a ground plane;
the ground plane having the shape of a semi loop;
the semi loop defining an opening; and
the opening defining a curve having at least five segments that are connected in such a way that each segment forms an angle with any adjacent segments, such that no pair of adjacent segments define a larger straight segment.

Abstract
This invention refers to an antenna structure for a wireless device comprising a ground plane and an antenna element, wherein the ground plane has the shape of an open loop. The invention further refers to an antenna structure for a wireless device, such as alight switch or a wristsensor or wristwatch, comprising an open loop ground plane having a first end portion and a second end portion, the open loop ground plane defining an opening between the first end portion and the second end portion; and an antenna component positioned within the opening defined between the first end portion and the second end portion and overlapping at least one of the first end portion or the second end portion. Further the invention refers to a corresponding wireless device and to a method for integrating such an antenna structure in a wireless device.
