2.4GHz天线在WAPI中的应用

一种2.4GHz天线在WAPI中的应用

内容简介：介绍了一种工作频率在2.4 GHz应用于无线局域网鉴别和保密基础结构（Wireless LAN Authentication and Privacy Infrastructure,WAPI）标准的天线,天线采用现在广泛应用于ISM频段的平面倒F天线（Plane Inversion-FAncenna,PIFA）形式。阐述了PIFA的演变过程及其理论基础。根据传统的PIFA设计了一款应用折叠技术的PIFA,达到天线小型化的目的。制作出产品后天线尺寸只有8.85 mm×36.5 mm。该天线外形紧凑,成本低廉,能完全覆盖2.4~2.483 GHz ISM频段。

Abstract：This paper discusses an 2.4 GHz antenna used in WAPI.The antenna is a compact plane inversion-F antenna（PIFA） which is widely used in ISM-band.This paper briefly expounds the evolution process and theoretical basis of the plane inversion-F antenna.It designs a PIFA antenna using folding technology basedon traditional plane inversion-F antenna for antenna miniaturization.The size of antenna product manufactured by this design method is only 8.85 mm×36.5 mm.The antenna has compact form and low cost,and it can fully cover ISM frequency range of 2.4~2.483 GHz.
