Abstract

A dual-band antenna designed at the wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) bands is presented compact split circular ring shape dual-band antenna with open ring and addition strip. Its size is compact by the recondition circular ring shaped resonator connected. The antenna is fabricated onto a printed circuit board (PCB) on FR-4 substrate and the relative permittivity of 4.4, an overall size of 23 mm × 30 mm × 0.8 mm. This antenna can easily adjusted with open ring and strip to match impedance using a 50 ohm transmission line with SMA connector. The measured results show that the compacted antenna achieves a dual-band operating bandwidth from 2.38 GHz to 2.56 GHz and 4.66 GHz to 7.29 GHz for 11 |S||| below -10 dB and the antenna yields omnidirectional patterns. The measured gains of the antenna from 2.45 and 5.5 GHz frequencies are 1.55 dBi and 3.2 dBi, respectively.

紧凑型分环环形双频天线，带开环和附加带

提出了一种适用于无线局域网(WLAN)和全球互操作性微波接入(WiMAX)频段的双频天线，采用开环加带的紧凑型开环双频天线。其体积小巧，由修复的环形谐振器连接。该天线制作在FR-4衬底上的印刷电路板(PCB)上，相对介电常数为4.4，整体尺寸为23 mm × 30 mm × 0.8 mm。这种天线可以很容易地调整开环和条带，以匹配阻抗使用50欧姆传输线与SMA连接器。测量结果表明，该压缩天线在-10 dB以下的11 S范围内实现了2.38 GHz ~ 2.56 GHz和4.66 GHz ~ 7.29 GHz的双频工作带宽，并产生了全向方向图。天线在2.45 GHz和5.5 GHz频段的实测增益分别为1.55 dBi和3.2 dBi。
