| 摘 要： | 针对无线局域网(WLAN)通信技术的要求,设计了一副小型化WLAN双频天线。利用Hilbert分形曲线和倒L型加载分别在低频和高频段获得了98 MHz(2395 MHz～2503 MHz)和2 200 MHz(4160 MHz～6360 MHz)的阻抗带宽(S11≤10 dB)。制作了天线实物并测量,仿真与测试结果吻合良好,天线在工作频带内具有全向辐射性能。天线整体尺寸仅为0.16λl×0.128λl,非常有利于WLAN天线的小型化应用。

| Abstract: | A novel miniaturized dual-band antenna was designed for WLAN communication technology.It has obtained a impedance bandwidth of 98 MHz(2 395 MHz~2 503 MHz)and 2 200 MHz(4 160 MHz~6 360 MHz)(S11≤-10 dB),with a Hilbert fractal curve and a invert-L loaded in the antenna.A WLAN antenna was fabricated and measured,the simulation and measured results are in good agreement,and the antenna exhibits omnidirectional radiation in the operating frequency band.The antenna is favored for miniaturized application in WLAN for the 2-D size of the antenna is only 0.16 λl×0.128 λl. |
