New Description: [New Technology Area] This creation is about a contact-type gain-enhanced exposed metal antenna, especially one that can contact the antenna radiator on the surface of the casing and the good conductor outside the casing. Increase the antenna radiation area to increase the antenna gain. [Prior Art] Many portable wireless electronic products can integrate antennas of several frequency bands into one multi-frequency antenna, but the use of relatively low frequency cannot be integrated, such as FM FM antenna, global FM broadcast signal frequency. The range is about 65·8ΜΗζ to 108MHz. Due to the low frequency and long wavelength, the FM antenna size must be large. It is not easy to design in portable electronic products. The current FM broadcast antenna uses headphones as the FM antenna. The user must carry the earphones to listen to the broadcast content, which is extremely inconvenient; although the m-chip antenna and the wound antenna can be placed inside the device, it has great interference to nearby circuits, and the antenna radiation efficiency is not good due to the size limitation. The noise is serious when listening to the radio, and only when it is moved to the open space such as the window can it be improved. In the patent case of the Republic of China invention patent number M352142 "antenna structure of metal case mobile phone", a metal phone case structure is disclosed, which has the grounding leg of the antenna structure, the grounding of the printed circuit board, and the metal material. The front cover is electrically connected. It is obvious that the antenna structure in this case does not design the antenna radiating portion on the surface of the insulator housing. In the patent case of the Republic of China invention patent number M349〇5〇 "can be used for metal M379862 shell or non-metal shell hand" antenna j, the disclosure of the kind, and the antenna along the circuit board inside the phone The edge of the ring is similar to the f. The middle position of the 卩 is cut off, and the conductive connection is made to the metal structure, and the metal casing is not electrically connected to the surface of the insulator.
