摘要

本文研究了一种称为“指向性”的新特征在锥形槽天线中的应用。该导向器以前是为平衡对映维瓦尔第天线设计的，由在天线孔径中引入的高介电剖面组成。它的作用是通过将辐射能量集中在射末方向来提高天线近场的指向性。仿真结果表明，该导流器对锥形槽的设计非常有利。

Enhanced directivity of a tapered slot antenna for near-field imaging

This paper investigates the application of a novel feature called the “director” to a tapered slot antenna. This director, previously designed for a balanced antipodal Vivaldi antenna, consists of a profiled piece of higher dielectric introduced in the antenna aperture. Its effect is to increase the antenna directivity in the near-field by focusing the radiated energy in the end-fire direction. Simulated results show that the director may be highly beneficial for the tapered slot design.
