应用于无线局域网的小型化宽带天线

内容简介：文章提出一种适用于无线局域网的新型小型化宽带天线。该种天线能在所需的频带产生相应的谐振模式，能完全覆盖5-GHz无线局域网频段。该天线采用同轴馈电并印刷在FIK4介质基片上。天线结构应用Ansoft HFSS软件进行设计和优化仿真，仿真结果显示：天线在IEEE802．11a无线局域网频段带宽为3．69GHz，而且在频带内能获得良好的辐射特性。完全适用于WLAN系统应用。

Abstract：This letter shows a novel and compact wideband antenna for wireless local area network （WLAN） applications. The proposed antenna effectively covers 5-GHz wireless local area network bands with corresponding resonance patterns. The proposed antenna is fed by the coaxial and Printed on the FR4 substrate.The antenna structure is designed and optimized with a 3D simulation software Ansoft HFSS. The simulation result indicates that the antenna achieves the bandwidth of 3.49GHz at IEEE802.11a; and the antenna can obtain good radiation characteristics in the band. This novel antenna is completely suitable for WLAN system.
