| 摘 要： | 提出了一种应用于无线局域网(WLAN)的新型低成本多频段天线,采用斜切角接地的平面单极结构,天线顶部折返成水平面内的两个对称矩形单元来降低高度。同时,通过在垂直辐射单元表面开L形槽的方法,实现了无线局域网高低两个工作频段覆盖的需求。天线在各工作频段内具有良好的全向辐射特性。实测和仿真结果基本吻合,从而验证了这种设计方法的有效性。

| Abstract: | An improved low cost multi-band shorted planar monopole antenna with a bevel is presented for wireless local area network(WLAN).Two parasitic elements at the top of the antenna can not increase the height of antenna and can widen bandwidth.Compared with conventional monopole antenna,this antenna can produce wider frequency bandwidth by adding L-type slot in vertical radiation element. The simulated bandwidths for the lower and upper bands are able to cover the whole WLAN.In addition,good omnodirectional radiation characteristic over the operating bands are obtained.The measurement and simulation results are in good agreement,which validates the proposed design. |
