摘要

介绍了一种适用于2.4/5.2/5.8 ghz无线局域网(WLAN)应用的紧凑型双频天线。天线由两个单元组成，一个C形单元和一个E形单元。这两种元件都导致双频段工作时两种谐振模式的不激励。c形元件直接由同轴探头馈送。已成形元件使用连接圆柱通孔与接地面耦合。进行了彻底的参数研究以优化天线性能。所设计的天线在覆盖WLAN频率的下频段提供约114MHz (2.32GHz - 2.46GHz)的带宽，在上频段提供约2.58GHz (4.48GHz - 7.46GHz)的带宽。天线辐射方向图在全带宽上呈宽边方向图，最大增益约为1.5dBi。与之前的研究相比，天线的面积缩小了50%。

Compact Dual – Band Antenna for 2.4/5.2/5.8-GHz WLAN Applications

A compact dual – band antenna for 2.4/5.2/5.8-GHz wireless local area network (WLAN) applications ispresented. The antenna consists of two elements, a C shapedelement and a E shaped element. Both of these elements result inexcitation of two resonant modes for dual – band operation. TheC shaped element is fed directly with coaxial probe. The Eshaped element is coupled with ground plane using a connectingcylindrical via. A thorough parametric study is performed tooptimize the antenna performance. The designed antennaprovides bandwidths of about 114MHz (2.32GHz – 2.46GHz) over the lower band and 2.58GHz (4.48GHz – 7.46GHz) over theupper band covering the WLAN frequencies. The antennaradiation pattern shows a broadside pattern over entirebandwidth with maximum gain of about 1.5dBi. The size of theantenna is reduced by 50% in terms of area compared to theprevious research.
