Abstract

Recently the microstrip patch antennas (MPA) has evolved into a most dynamic and indigenous field in the arena of UWB demanding low profile and mini antennas with ample frequency choice for ultra wide (UWB) applications. Thus the paper focuses on thorough analysis of a novel rectangular microstrip patch with carpet shaped fractal antenna fed by microstrip line for applications in Ultra- Wideband. The basic antenna structure is rectangular microstrip patch which is modified by adding slotted rectangular shape with partial ground plane at the rear end is iterated using fractal geometry that exhibits more bandwidth and reduce return loss. The proposed antenna has a compact size 50×42mm2 with height 1.6mm and designed on low cost FR4 (er = 4.3) substrate. A wider bandwidth (-10 dB) of around 3.1 – 8.25 GHz with stable radiation pattern is achieved and E-field, H-field current distributions are also examined. When compared with the existing traditional UWB antennas, the recommended antenna exhibits good characteristics, low profile and more so cost-effective. By using CST MW studio software the Proposed UWB antenna is designed and simulated to verify antenna parameters for improvements.

用于超宽带应用的微带矩形地毯形分形天线

近年来，微带贴片天线(MPA)已发展成为超宽带领域中最具活力和独创性的一个领域，该领域对超宽带应用要求低轮廓和微型天线，并提供充足的频率选择。因此，本文重点对一种应用于超宽带的新型带地毯形分形天线的矩形微带贴片进行了深入分析。该天线的基本结构为矩形微带贴片，通过增加后端部分接平面的开槽矩形形状进行改进，采用分形几何迭代，使其具有更大的带宽和更低的回波损耗。所提出的天线具有紧凑的尺寸50×42mm2，高1.6mm，设计在低成本FR4 (er = 4.3)基板上。在3.1 ~ 8.25 GHz范围内获得了更宽的带宽(-10 dB)，辐射方向图稳定，并对e场、h场电流分布进行了测试。与现有的传统超宽带天线相比，所推荐的天线具有良好的特性、低姿态和更高的性价比。利用CST MW studio软件对所提出的超宽带天线进行了设计和仿真，验证了天线的参数，以进行改进。
