摘要

本文介绍了一种用于毫米波应用的优化宽带波束导向天线系统的性能。该天线是无源的，可以在仰角上从舷侧方向和方位角上的任何方向提供高达$\pm \mathbf{40}^{\mathbf{o}}$的连续二维波束扫描。它使用一对近场介电相位变压器，灵感来自光学棱镜，从源天线引入预先确定的相位梯度到入射波前，并将辐射波束重定向到指定方向，顶点角为80°的锥形区域。天线系统的原型以及安装结构已经制造和测试。

A Wideband Wide-Angle Beam-Steering System for Millimeter-wave Applications

This paper presents the performance of an optimized wideband beam-steering antenna system for mm-wave applications. The antenna is passive and can provide continuous two-dimensional beam scanning up to $\pm \mathbf{40}^{\mathbf{o}}$ away from broadside direction in elevation and any direction in azimuth. It uses a pair of near-field dielectric phase transformers, inspired from optical prisms, introducing a pre-determined phase gradient to the incoming wave front from a source antenna, and redirecting the radiated beam to specified direction with in a conical region with an apex angle of 80°. A prototype of the antenna system along with the mounting structure has been fabricated and tested.
