摘要

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, wherein 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 just 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 the 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 the high-frequency frequency band.
