Abstract
An antenna structure includes a loop radiation element, a balance radiation element, a first additional radiation element, and a second additional radiation element. The loop radiation element has a first feeding point. The balance radiation element has a second feeding point. The balance radiation element is coupled to at least a first connection point on the loop radiation element. The balance radiation element is substantially surrounded by the loop radiation element. The first additional radiation element is coupled to a second connection point on the loop radiation element. The second additional radiation element is coupled to a third connection point on the loop radiation element. The loop radiation element is disposed between the first additional radiation element and the second additional radiation element.

An antenna structure, comprising:
- a loop radiation element, having a first feeding point;
- a balance radiation element, having a second feeding point, and coupled to at least a first connection point on the loop radiation element, wherein the balance radiation element is substantially surrounded by the loop radiation element;
- a first additional radiation element, coupled to a second connection point on the loop radiation element;
- and a second additional radiation element, coupled to a third connection point on the loop radiation element;
- wherein the loop radiation element is disposed between the first additional radiation element and the second additional radiation element;
- wherein the antenna structure generates an isotropic radiation pattern wherein the balance radiation element comprises a first branch portion, a second branch portion, and a connection portion, and wherein the connection portion is coupled between the first branch portion and the second branch portion;
- wherein the connection portion is directly connected to the first connection point.
