基于手机屏蔽罩的新型天线结构设计

New Antenna Structure Design based on Mobile Phone Shield-Can

基于手机金属屏蔽罩提出了一种新型天线结构设计。该设计充分考虑目前手机对天线小型化、低成本、高性能、多频带复用的要求,利用手机本身的屏蔽罩金属部件及其与主板间隔的特点,进行分区隔栅设计,使得该屏蔽罩具备屏蔽保护手机内部敏感器件和实现手机天线辐射的双重功能,既降低了开发成本,又节省了手机内部空间。仿真与测试结果表明:该新型天线设计带宽为0.5～3 GHz,满足手机多个频段通信要求,且具有良好的性能和全向辐射性。

A new antenna structure The design, by fully considering the design based on the metal shield-can of the mobile phone is proposed. current requirements of miniaturization, low cost, high performance and multi-band multiplexing of mobile phones, and utilizing the shielding metal parts of mobile phone itself and its separation from the main board for the design of partition barrier, makes the shield-can have the dual functions of shielding and protecting the internal sensitive components of the mobile phone and realizing the radiation of the mobile phone antenna, thereby reducing the development cost and saving the space inside the mobile phone. The simulation and test results indicate that the newly-designed antenna, with the bandwidth of 0.5 to 3 GHz, can meet the requirements of communication in multiple frequency bands of mobile phones, and has good performance and omnidirectional radiation.
