提出一种平面三频单极子手机天线,该天线通过对天线辐射贴片进行弯折、开缝等手段在单一天线上实现三频。天线的工作频段完全覆盖了GSM900M(890MHz～915MHz),DCS1800M(1.71GHz～1.88GHz),Bluetooth(2.4 GHz～2.48 GHz)的所有频率,工作性能良好。该天线结构易于实现,便于集成,适合在移动通信中大规模使用。
A planar tri-band monopole mobile phone antenna is proposed. The antenna realizes tri-band on a single antenna by means of bending and slotting the antenna radiating patch. The operating frequency band of the antenna completely covers all frequencies of GSM900M (890MHz ~ 915MHz), DCS1800M (1.71GHz ~ 1.88GHz) and Bluetooth (2.4GHz ~ 2.48GHz), and works well. The antenna structure is easy to implement, easy to integrate and suitable for large-scale use in mobile communications.
