摘　　要：提出一种新型U型开槽的平面倒置F型双频微带天线(PIFA),该天线利用单馈点同轴线馈电,辐射贴片尾端折叠的设计方式,其结构实现了微带天线在无线通信中小型化双频段工作的要求。利用著名的ANSOFT公司的仿真软件HFSS8. 0 (HighFrequencyStructureSimulator)进行仿真设计和优化,最终仿真设计了一副适用于GSM900MHz/DCS1800MHz通信系统的微带天线。This paper describes a novel dual-band planar inverted-F antenna (PIFA) loaded with a U-shaped slot. The proposed PIFA uses a single coaxial feed and the end of the radiating patch is folded up for the miniaturization. The purpose of this paper is to achieve a compact dual-band antenna for GSM 900 MHz/DCS 1800 MHz system. Simulated results are computed by the software Ansoft HFSS8.0 (High Frequency Structure Simulator).
