How to improve an antenna that is efficient and suitable for installation in various notebook computers has always been the direction sought by the industry. Q provides a solution in the case of the Republic of China Invention Open Bulletin No. 200713705 "Multi-Frequency Antenna Structure". The system mainly has a ground plane, a first radiating metal arm, a first parasitic short metal arm and a second parasitic short metal arm. The first parasitic short metal arm and the second parasitic short metal arm are respectively resonated with the first radiating metal arm to form two gamma bands to form a multi-frequency effect. Since the previous structure is wound in a rod shape (I_bar), since the structural relationship must be fixed, the holder can be fixed. Therefore, the combination has its shortcomings and needs to be modified. [Summary] The arm and the main supply The F-drum line mainly has a health-spoke W, a high-frequency light-wire line, and the high-frequency wheel end portion of the local frequency is extended upwards, and the muscle line is set at the feed point from the early k諕. The main signal line is connected to the high 200919830 frequency radiating arm. A loop is formed by the ground-to-feed point connection to cause a high frequency effect on the antenna. The inverted-F antenna provided by the invention can be directly wound into a hollow long rod shape (I-bar) or attached to a flexible board to reduce the entire antenna volume, and is suitable for assembly in various notebook computers. . Hereinafter, the structural features and operational effects of the present invention will be described in detail based on the embodiments shown in the drawings. [Embodiment] Referring to the first and second figures, the inverted-F antenna provided by the present invention is mainly composed of a low-frequency radiation arm 10, a high-frequency radiation arm 2〇, and a main signal line 3〇.
