Abstract

Aims of this study are to design a simple and compact microstrip-fed Ultra Wide Band (UWB) printed fractal antenna and analyze the performance of the antenna for different iterations. A second iteration of a triangle patch antenna is proposed to perform UWB. Based on the result, the proposed antenna occupies about 6.73 GHz bandwidth covering 3.52-10.24 GHz. The bandwidth is increased about 54.15% for the first iteration of proposed antenna and 69.5% increased for second iteration. A radiation pattern in H-plane and E-plane is also obtained. H- plane of radiation pattern is performed as omni directional and E-plane perfomed like a dipole antenna. Coplanar wave guide is approached to obtain ultra wideband.

分形天线的超宽带应用分析
本研究的目的是设计一种简单、紧凑的微带馈电超宽带(UWB)印刷分形天线,并分析该天线在不同迭代下的性能。提出了一种二次迭代的三角形贴片天线来实现超宽带。结果表明,该天线的带宽约为6.73 GHz,覆盖3.52 ~ 10.24 GHz。该天线第一次迭代的带宽增加约54.15%,第二次迭代的带宽增加约69.5%。得到了h平面和e平面的辐射图。辐射方向图的H面表现为全向,e面表现为偶极子天线。利用共面波导获得超宽带。
