摘要
本文重点介绍了两种不同的分形矩形微带贴片天线，用于低轮廓的多波段工作。采用RT/Duroid作为基片，εr为(2.2)，高度为(1.575mm)， Sierpinski Carpet和Minkowski两种分形几何对贴片天线进行了三次迭代设计，采用另一种基片FR4， εr为(4.4)，高度为(1.6mm)，对矩形微带贴片天线进行了同样的设计，天线结果为VSWR;利用HFSS v 15(高频结构模拟器)对天线进行了仿真，得到了天线的回波损耗和增益，并对不同衬底的回波损耗和增益进行了比较。并且能够在S和C波段工作。
Design and simulation of multiband fractal antenna with various geometries
Paper highlights two different fractal based rectangular microstrip patch antenna has proposed for multiband operation with low profile. The recommended design of antenna achieved by basic patch antenna using RT/Duroid as substrate of εr (2.2)and height of (1.575mm)and two fractal geometries are Sierpinski Carpet and Minkowski has applied on patch antenna and process carried up to three iteration, same process is carried on rectangular microstrip patch antenna using another substrate is FR4 εr of (4.4) and height of (1.6mm), the antennas results are VSWR, Return loss and gain is obtained by simulation and results of different substrate are compared, the simulation of proposed antenna is done using HFSS v 15 (high frequency structure simulator). And are able to operate in S and C band.
