摘　　要：基于当前通信技术飞速发展的需求背景,提出并设计了一种可应用于WLAN、WiMAX的微型的CPW(共面波导馈电)天线。该天线将L型枝节和开口谐振环与辐射贴片和共面波导地面相结合,采用环氧树脂FR-4作为介质基片,该基片可以满足天线的各种应用形式,固化也非常方便。天线整体尺寸很小,仅为31 mm×31 mm×0.8 mm。通过添加L型枝节和开口谐振环,激发了天线的两个谐振频点,拓宽了频带带宽(几乎全覆盖)。通过HFSS对天线进行仿真分析得出,天线可以工作在WLAN(2.4~2.48 GHz)、(5.0~5.15 GHz)和WiMAX(3.4~3.6 GHz)的频段上,并且有着良好的增益。Based on the rapid development of current communication technology,a micro CPW(Coplanar Waveguide feed) antenna which can be applied to WLAN and WiMAX is propoesd and designed. The antenna combines L-type branches and open resonant rings with a radiant patch and coplanar waveguide ground,using epoxy resin FR-4 as a dielectric substrate,which can meet a wide range of antenna applications and is very easy to cure. The overall antenna size is very small,only 31 mm×31 mm×0.8 mm.By adding L-type branches and open resonant rings,the two resonant points of the antenna are excited and the band bandwidth is widened(almost full coverage). Through the simulation analysis of the antenna by HFSS,the antenna can work in WLAN(2.4~2.48 GHz),(5.0~5.15 GHz) and WiMAX(3.4~3.6 GHz)band,and has a good gain.
