摘要

在c波段D/L 4Ghz (3.82Ghz-4.38Ghz)和U/L 6Ghz (5.92Ghz-6.19Ghz)的卫星下行链路和上行链路应用中,提出了一种叠置改进Sierpinski衬片分形天线,实现了双频特性和宽带。采用FR4 (r=4.4)衬底,衬底高度h=1.6mm,采用接近馈电技术设计。基于自相似特性,对二次迭代天线进行了改进。天线有4Ghz和6Ghz两个共振频率。达到了500mhz和300MHz左右的带宽,这对于卫星通信来说是相当高的。对天线的回波损耗、驻波比等性能进行了分析。利用IE3D软件对所提出的天线进行了仿真。

A stacked Sierpinski's gasket fractal antenna for satellite uplink/downlink application
In this paper a stacked modified Sierpinski's gasket fractal antenna is presented to achieve dual band behavior and wide bandwidth for satellite down link and uplink application in C-band D/L 4Ghz (3.82Ghz-4.38Ghz) and U/L 6Ghz (5.92Ghz-6.19Ghz) bands respectively. It is designed with proximity feeding technique using FR4 (∊r=4.4) substrate and height of the substrate h=1.6mm. Based on self similar properties modified to 2nd iteration antenna is proposed. The antenna has two resonance frequencies about 4Ghz and 6Ghz. About 500 MHz & 300MHz bandwidth has been achieved, which are reasonably high for satellite communication. The performance properties of antenna such as return loss, VSWR has been shown. Proposed antenna has been simulated using IE3D software.
