Abstract

A new approach in realization of Defected Ground Structure Microstrip Patch antennas with Fractal Slots cutin the ground plane has been presented. The presented approach resulted in miniaturization of radiating patches and avoidance of multiple resonances which are prime considerations in antennas for Wi-Fi applications. A rectangular Microstrip patch is taken as a basic radiating patch. In the ground plane, square and circular slots following Sierpinski Carpet Fractal Geometry are cut resulting in Defected Ground Structure (DGS) Microstrip Patch antenna. The antenna is designed to operate at 2.4 GHz and the performance characteristics have been simulated using HFSS software. The proto-type DGS Microstrip patch antenna with square fractal slots is fabricated and tested. The measured results are in good agreement with the simulation studies. The technique has also resulted in size reduction of radiating patch compared to the standard microstrip patch antenna operating at the same frequency.
用分形几何实现 DGS 微带贴片天线的新方法
本文介绍了一种在地平面上切割分形槽实现缺陷接地结构微带贴片天线的新方法。该方法实现了辐射贴片的小型化,避免了多重共振,而这正是 Wi-Fi 应用中天线的首要考虑因素。矩形微带贴片是基本的辐射贴片。在地平面上,按照西尔平斯基地毯分形几何原理切割出方形和圆形槽,从而形成了缺陷地层结构(DGS)微带贴片天线。该天线的设计工作频率为 2.4 GHz,其性能特性已通过 HFSS 软件进行了仿真。带有方形分形槽的原型 DGS 微带贴片天线已制作完成并进行了测试。测量结果与模拟研究结果十分吻合。与工作在相同频率的标准微带贴片天线相比,该技术还减小了辐射贴片的尺寸。
