摘　　要：双馈陶瓷双频手机内置天线,是一款体积小(长10 mm,宽3.2 mm,高1.5 mm)、重量轻、低剖面、可同时覆盖GPS和BT/WIFI频段的新型陶瓷手机内置天线,天线设计结构简单,通过在陶瓷表面的镀银层开槽,耦合出两个频段,天线敏感,但制作工艺精准度高,所以实用性好,通过CST软件的仿真优化,并用网络分析仪和ETS暗室对实物进行测试。仿真和测试结果都表明该天线性能良好,能够较好满足手机天线小型化和多频段的要求。Ceramic Dual Feed GPS/BT plane, has dual working bands of GPS and mobile phone antenna（10mm×3.2mm×1.5m m）, light weight and low section BT/WIFI, with small volume. The antenna is simple in structure, and the slot on the silver plane of the ceramic surface can couple two bands. The antenna is of high sensitivity, and thus requires high technological level of manufacture and is quite applicable. The antenna is simulated and optimized with CST software, and also tested with analytic instrument and ETS chamber. All these indicate that the designed antenna is of high performance and could satisfy the requirement of miniaturization and multi-bands by mobile-phone antenna.
