Abstract

This paper presents the design and experimental of dual wideband coplanar waveguide (CPW)-fed using stub split-ring rectangular slot antenna operates in WLAN applications. This antenna is designed for dual frequency used in WLAN system coverage IEEE 802.11b/g (2.4-2.4835 GHz) and IEEE 802.11a (5.15-5.35 GHz). The results of the return loss (S11), gain and radiation pattern of the proposed antenna have been simulated by using antenna analysis software IE3D program. The transmission line and ground plane have been designed to be on the same plane with antenna slot to be applicable for wideband operation. It is found that the proposed antenna is accessible to bandwidth about 40% and 15.47% at frequency range 2-3 GHz and 4.71-5.5 GHz, respectively. Measured maximum gains were approximately 6.74 dBi and 7.01 dBi for 2.45 GHz, 5.2 GHz band, respectively. Finally, simulation and measurement results for the design example are presented and a conclusion follows.

采用短节分环矩形槽天线的cpw馈电双宽带

本文介绍了一种基于短段分环矩形缝隙天线的双宽带共面波导馈电系统的设计与实验。该天线设计用于WLAN系统覆盖IEEE 802.11b/g (2.4-2.4835 GHz)和IEEE 802.11a (5.15-5.35 GHz)的双频。利用IE3D天线分析软件对天线的回波损耗(S11)、增益和辐射方向图进行了仿真。传输线和地平面设计为与天线槽在同一平面上，以适应宽带运行。结果表明，该天线在2-3 GHz和4.71-5.5 GHz频段分别可获得约40%和15.47%的带宽。在2.45 GHz和5.2 GHz频段测得的最大增益分别约为6.74 dBi和7.01 dBi。最后给出了设计实例的仿真和测量结果，并得出了结论。
