Description of the Invention: [Technical Field] The present invention provides a hook structure for a portable electronic device, and more particularly, a hook structure having a combined antenna element. [Prior Art] In a portable electronic device, such as a notebook computer, a PDA or a translator, etc., it is a folding structure, basically having a base and an opening and closing cover that can be folded or opened to each other, in general The base is a keyboard, and the opening and closing cover is a display screen. At the front edge of the opening and closing cover, a hook structure is provided, which acts to hook the base when folding to prevent the base and the opening and closing cover from opening. Due to the development of wireless rail verification, it is necessary to build at least one antenna structure with radiation function to receive signals. Due to the compaction requirements of portable electronic devices, the space in which the antenna structure can be set is more and more reduced. Therefore, how to design an antenna structure that does not occupy the internal space of a portable electronic device has been a subject of the industry's search.
