摘要

提出了一种适用于WLAN/WiMAX的多频段印刷单极天线。采用z形带，可获得以2.5 GHz和5.7 GHz为中心的双工作频段。为了实现以3.5GHz为中心的WiMAX应用频段，引入了h形带。研究了该天线的阻抗带宽、辐射方向图和实现增益等多波段工作特性。此外，还分析了天线对馈地尺寸变化的灵敏度。实测结果与模拟结果吻合较好。

Novel design of printed multiband antenna for wireless applications

A novel compact printed monopole antenna with multiple operating bands for WLAN/WiMAX is presented. By using a Z-shaped strip, dual operation bands centered at 2.5 and 5.7 GHz can be obtained. To achieve the WiMAX application band centered at 3.5GHz, an h-shaped strip is introduced. Several multiband operation characteristics of the proposed antenna, such as impedance bandwidth, radiation pattern, and realized gain have been investigated. Moreover, the sensitivity of the proposed antenna to the size variations in its feed ground has also been analyzed. The measured results are in good agreement with the simulated ones.
