Under the requirement of the recording (10), the (four) face of the antenna can be placed inside the notebook computer, which causes the antenna of the Wei brain to be inspected at the time of design. Even if the frequency is adjusted by the resonance method, since the _ resonance of the antenna becomes a false resonance, the high-efficiency structure of the original antenna is destroyed, and the performance is worse, which needs to be improved. SUMMARY OF THE INVENTION The main design object of the present invention is to make the antenna structure with insufficient antenna structure or unable to reach the required bandwidth to complement the bandwidth of the antenna and have better performance. The antenna structure of the notebook computer provided by the present invention is composed of an antenna body and a printed circuit board. The printed circuit board is disposed on the antenna body and electrically connected, and the printed circuit board is provided with a wireless radio frequency matching circuit, and the wireless radio frequency matching circuit can adjust the required bandwidth, and the space is reduced to affect the antenna body. Effective energy. The structure and operation work of the present invention will be described in detail below based on the embodiments shown in the drawings. [Embodiment] Referring to the first and second figures, the antenna structure of a notebook computer provided by the present invention is one day. The line body 10 and a printed circuit board 20 are formed. The antenna body 1 is made of metal. As shown in the figure, the antenna body 1 is a kind of planar antenna, and a plurality of slots are formed between the feeding end and the grounding end to form two radiating elements to form different current loops to achieve wide frequency. antenna. m
