Electronic device with embedded antenna

1. An electronic device with an embedded three-dimensional antenna, the electronic device comprising:

a printed circuit board (PCB); and

an embedded three-dimensional antenna comprising:

a radiation element; and

a connection element comprising a first connection part and a second connection part, the first and second connection parts, respectively coupled to the PCB, for transferring signals of the embedded three-dimensional antenna to the PCB;

wherein the first and second connection parts clamp the PCB such that the embedded three-dimensional antenna is attached on the PCB; wherein the connection element is formed at one end of the radiation element; and wherein the first and second connection parts respectively comprise a notch, for attaching a distance from the radiation element to the lateral of the PCB.

2. The electronic device of claim 1 , wherein the embedded three-dimensional antenna further comprises a clamping element, formed at another end of the radiation element as an auxiliary of the connection element.

3. The electronic device of claim 1 , wherein the first and second connection parts are a feeding terminal and a grounding terminal of the embedded three-dimensional antenna, respectively, and are coupled to metal contacts of the PCB.

4. The electronic device of claim 1 , wherein tail ends of the first and second connection parts have an outward warped mechanism, respectively.

5. The electronic device of claim 1 , wherein the radiation element is a bended metal sheet disposed on a lateral of the PCB.

6. The electronic device of claim 1 , wherein the radiation element is a bended metal sheet disposed on one side of the PCB.

7. The electronic device of claim 1 , wherein the embedded three-dimensional antenna is formed by a single metal sheet.

8. The electronic device of claim 1 , wherein the embedded three-dimensional antenna is a planar inverted-F antenna (PIFA).
