摘　　要：设计了一款多频段小型宽带单极子天线。采用Ansoft公司的HFSS13电磁仿真软件,对天线进行了仿真及优化,天线尺寸为39mm×29mm×1.7mm,该天线在多个频率点上谐振。仿真结果表明,该天线参数S11≦-10 d B,天线和馈线匹配的很好,覆盖了LTE2300,LTE2500和WLAN的2.4/5.2/5.8 GHZ及Wi MAX的2.5/5.5 GHz的工作频段,适于目前的超薄智能手机。A compact multi-broadband planar monopole antenna is proposed and designed.The antenna is simulated and optimized with electromagnetic simulation software HFSS13.0（ High Frequency Structure Simulator）.The antenna is 39 mm × 29 mm × 1.7mm in size and resonates at mutiple frequencies.Simulation results show that with parameter S11 ≦-10 dB,the proposed antenna could match well with its feed-line and cover many useful operation frequency bands,including LTE2300,ISM,LTE2500,WLAN,Wi MAX,thus is fairly suitable for the present ultra-thin smart phones.
