摘要

本文介绍了一种采用阿基米德螺旋设计的负折射率超材料(NIM)改进对倒维瓦尔第波纹天线。单层NIM片垂直放置在拟议天线的两个臂的中间。天线尺寸为30×60×0.787 mm3，工作频率为8GHz。对NEVI波形对映维瓦尔第天线的仿真结果表明，该天线的增益和指向性分别提高了1.2dB和1dB。在超宽带应用中，从4.7 GHz增加到11 GHz时，HPBW增加了90倍，反射系数小于DIO dB。

Corrugated antipodal Vivaldi antenna using spiral shape negative index metamaterial for ultra-wideband application

This paper describes a corrugated antipodal Vivaldi antenna with improved performance by using negative index metamaterial (NIM) of the Archimedean spiral design. A single layer NIM piece is placed perpendicular middle of the two arm of the proposed antenna. The antenna size is 30×60×0.787 mm3 operating at 8GHz. The simulated results of NEVI corrugated antipodal Vivaldi antenna show that the gain and directivity has increased up to 1.2dB and 1dB respectively. The HPBW is increased by 90 with the reflection coefficient less than DIO dB from 4.7 GHz to 11 GHz for UWB application.
