摘要

本文提出了一种在不增加天线尺寸的情况下提高定向维瓦尔第天线增益的方法。基于电场相位差校正理论，在天线中增加了相位补偿透镜。为了便于评估该方法的优点和局限性，我们使用了最基本的单元胞，矩形单元胞来构建透镜。我们的天线在ka波段(26- 40ghz)具有良好的阻抗匹配。在天线尺寸不变的情况下，该方法可使天线增益增强0.4 ~ 1.4 dBi。

Investigation of phase compensation lens to improve the gain of Vivaldi antenna in Ka-band

We present in this paper a method to increase the gain of our directive Vivaldi antenna without increasing the size of the antenna. Based on the theory of E-field phase difference correction, a phase compensation lens (PCL) has been added to the antenna. The most basic unit cell, rectangular unit cell, has been used to build the lens to facilitate the evaluation of the advantages and the limitations of this method. Our antennas have a good impedance matching in the Ka-band (26-40 GHz). The antenna gain enhancement is about 0.4 - 1.4 dBi using this method while the size of the antenna is unchanged.
