| 摘 要： | 提出了一种应用于无线局域网（WLAN）通信的三馈圆极化微带天线。天线在2300～2600MHz频带内实现圆极化辐射。天线馈电网络采用三功分馈电,增加了轴比带宽;馈电网络和附加的寄生贴片展宽了阻抗带宽;延伸天线介质衬底增大了波束宽度。仿真与实测结果吻合良好。测量结果表明,天线的阻抗带宽达到46.8%（VSWR〈2）,轴比带宽达到12.2%（AR〈3dB）。

| Abstract: | A circular polarization microstrip antenna with three feeds for WLAN applications is presented.The proposed antenna can realize circularly polarized radiation at 2300-2600MHz.The feeding network adopts a one-three power divider which can increase the bandwidth of axial ratio.The bandwith is greatly increased by this feeding network and the parasitic patch.The beamwidth is broadened by extending the size of dielectric substrate of antenna.A good agreement is achieved between the simulation and experiment res... |
