手机天线设计中地的常见处理方式

Grounding Solution in the Antenna Design of Mobile Phone

摘要: 总结了手机实际设计中地对天线性能的影响和常规解决方法，特别是金属壳体手机和超薄手机中通过对接地的选择和地分布的处理，对天线性能的优化起到了较大的作用。在SAR 设计中，对地的良好处理，也帮助降低手机对人体的辐射。手机天线性能的提升在于手机整体的优化设计。

Abstract: The grounding way in the antenna design of mobile phone are presented. It is shown from the data of somepractical design that appropriate grounding will improve antenna performance. And it is also helpful to make SAR lower.Antenna performance is decided by the design of the whole phone.
