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.
Description
technical field [0001] Embodiments of the present invention relate to antenna technology, and in particular to a built-in antenna of a reconfigurable mobile phone and an implementation method thereof. Background technique [0002] The antenna performance of mobile phone antenna design faces two difficulties. One is how to obtain a larger bandwidth as much as possible when working in the low frequency band, and the other is how to control the specific absorption rate (Specific Absorption Rate, SAR) of electromagnetic radiation when working in the high frequency band. (Indicators to measure the intensity of electromagnetic radiation from mobile phones) increased. Commonly used mobile phone antennas generally have two solutions: Monopole antenna and PIFA antenna. The Monopole antenna has a wider bandwidth and higher SAR, while the PIFA antenna has a narrower bandwidth and lower SAR. In the prior art, it is difficult to obtain the best performance experience in a limited space ...
