摘要

为了通过解决传统维瓦尔第天线的低增益问题来扩展传统维瓦尔迪天线的应用，本文在分析电介质单元传输特性的基础上，利用人工电磁材料的优势，结合维瓦尔第孔径的相位分布。提出了一种更合理的介质透镜加载方法，并将其与边缘开槽相结合。对结果的比较表明，天线工作在4-16的频率范围内 GHz。低频升压约为3 dB，高频升压约为9.6 dB。

A High Gain Vivaldi Antenna with Multiple Near-Field Dielectric Lenses and Grooved Edges

In order to expand the applications of the traditional Vivaldi antenna by addressing the low gain of the traditional Vivaldi antenna, this paper combines the phase distribution of the Vivaldi antenna aperture based on the analysis of the transmission characteristics of a dielectric unit by utilizing the advantages of artificial electromagnetic material. A more reasonable method of loading a dielectric lens is proposed and utilized in combination with edge grooving. A comparison of the results shows that the antenna operates in the frequency range of 4 to 16 GHz. The low-frequency boost is approximately 3 dB, and the high-frequency boost is approximately 9.6 dB.
