Antenna structure for a wireless device with a ground plane shaped as a loop
First Claim
1. An antenna structure for a wireless device comprising:
- a ground plane having an elongated shape and having two end portions, wherein the ground plane is at least partially integrated in a flexible strap, andan antenna element located in the proximity of one of the end portions,wherein when the flexible strap is bent, the ground plane defines an open loop and the antenna element is located within an area defined by the open loop.

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.
