摘要

双频天线覆盖IEEE 802.11a/b/g频段，采用小型化ii型单极天线，改进矩形带状地平面，用于2.400-2.484 GHz、5.150-5.350 GHz和5.725-5.825GHz频段的双频WLAN工作。将ii型单极天线和修改后的矩形接平面蚀刻在一块总尺寸为25mm × 44mm × 1.6 mm的印刷电路板(PCB)上。该天线可以很容易地通过带SMA连接器的50欧姆传输线馈电以匹配阻抗。测量结果表明，小型化天线实现了2.26 ~ 2.89 GHz和4.92 ~ 5.83 GHz的宽工作带宽;- 10db和全向辐射方向图。天线在2.400 ~ 2.484 GHz和5.150 ~ 5.825 GHz频段的实测增益分别为1.3 dBi和2.5 dBi。

Miniaturized dual-band II-shaped monopole antennas with modified rectangular ground plane

Dual-band antenna covering IEEE 802.11a/b/g bands is presented using a miniaturized II-shaped monopole antennas with modified rectangular strip ground plane for dualband WLAN operation over the frequency band of 2.400-2.484 GHz, 5.150-5.350 GHz and 5.725-5.825GHz. The II-shaped monopole antenna and with modified rectangular ground plane are etched onto a piece of printed circuit board (PCB) with an overall size of 25 mm × 44 mm × 1.6 mm. This antenna can easily be fed by strip line to match impedance using a 50 ohm transmission line with SMA connector. The measured results show that the miniaturized antenna achieves a broad operating bandwidth of 2.26-2.89 GHz and 4.92-5.83 GHz for |S11|<; -10 dB and omnidirectional radiation pattern. The measured gains of the antenna from 2.400 to 2.484 GHz and 5.150 to 5.825 GHz frequencies are 1.3 dBi and 2.5 dBi, respectively.
