RECONFIGURABLE MOBILE PHONE BUILT-IN ANTENNA AND IMPLEMENTATION METHOD THEREOF

摘要

The invention provides a reconfigurable mobile phone built-in antenna and an implementation method thereof. The reconfigurable mobile phone built-in antenna comprises an antenna main structure, an additional ground area, a ground area printed on one surface of a printed board, an electronic switch and an antenna feeding point and a grounding point printed on the other surface of the printed board, the antenna main structure comprises a wiring structure of the antenna, a feeding spring piece which is in contact with the antenna feeding point and a grounding spring piece which is in contact with the grounding point, and the additional ground area is positioned under the wiring structure; the electronic switch is used for disconnecting the additional ground area with the ground area on one surface of the printed board when the antenna works at low-frequency frequency band and connecting the additional ground area with the ground area on one surface of the printed board when the antenna works at high-frequency frequency band. The reconfigurable mobile phone built-in antenna can lead the mobile phone antenna to acquire the optimal wireless performance in finite space.
