New description: [New technical field] This creation is about an antenna structure (Antenna Structure), and especially related to a built-in The antenna structure of the electronic device. [Prior Art] • With the development of wireless communication technology, many electronic products that provide wireless communication functions have appeared on the market today. These, for example, mobile phones (Mobile phones) and notebook computers (N〇teb〇〇k) have a wide range of electronic products that use wireless communication technology to transmit information. As far as communication products are concerned, the key to the design is the antenna design, because the quality of the antenna design is good or not, which will affect the quality of communication. As mentioned above, in view of the fact that mobile phones and notebook computers have become indispensable electronic products in life, the industry will set up an antenna for receiving/sending mobile phone signals in the notebook computer to enhance the notebook computer. The functions, for example, in the prior art, the size of the mobile phone antenna is 11 〇•mmX5 mmx6 mm, and the signal receiving/transmitting band of the mobile phone antenna is 900 MHz, 1800 MHz and 1900 MHz. • However, because the notebooks on the market are all designed to be thinner and lighter, how to improve the size of the above-mentioned antennas makes it possible to configure the antennas in a limited space inside the notebook computer. In addition, antennas that have been reduced in size or changed in structure are usually unable to maintain their signal reception/wei gambling, that is, the sky-like reception/transmission band ^ conforms to the frequency band used by the mobile phone. Therefore, how to reduce the size of the antenna can still make the signal receiving/transmitting frequency band of the antenna conform to the use of mobile phones. 5 M309760 095-11-S510-U-TW 21513twf.doc/t The frequency band is another important issue.

The antenna structure is cut and folded from a metal piece, and the antenna structure includes a ground plate, an RF board, and a short circuit board. The ground plate has a body and a bent portion extending from the body. The radio frequency plate is disposed above the grounding plate, and an auxiliary radio frequency plate is extended. The distance between the folded portion and the radio frequency plate is smaller than the distance between the main body and the radio frequency plate. In addition, one end of the shorting plate is connected to the ground plate, and the other end of the shorting plate is connected to the radio frequency plate. • In one embodiment of the present invention, the ground plate and the radio frequency plate are parallel to each other, and the short circuit plate is perpendicular to the ground plate and the radio frequency plate.

An RF board 120 and a short circuit board 130 are formed. The grounding plate 110 of this embodiment is, for example, a grounding metal piece (the length of the grounding plate is, for example, 55 mm, and the width is, for example, 5 mm), and has a body 112 and a bent portion 114 extending from the body 112 (the length of the bending portion) For example, l8mni). The RF board 120 is, for example, a metal piece. The RF board 120 is disposed above the ground plane 110. The ground plane 110 is parallel to the RF board 120, for example, and the distance H1 between the bent portion 114 and the RF board 120 is smaller than the body 112. The distance H2 from the radio frequency board 120 (the distance between the ground plane and the radio frequency board is, for example, 6 mm). Further, the short-circuiting plate 130 is, for example, a metal piece, one end of the short-circuiting plate 130 is connected to the grounding plate 110, and the other end of the short-circuiting plate 130 is connected to the radio frequency plate 120.
