摘要

在这项工作中,提出了一种形成辐射孔径近场的方法。尽管该技术是通用的,但它适用于在30ghz下形成12λ聚焦孔径的焦点图案的特定场景。其主要结果包括在不影响光斑直径的情况下缩小/扩大焦深的能力。为了验证这一概念,将获取的孔径分布映射到已制造和测量的径向线槽天线(RLSA)上,取得了良好的效果。

3D focal spot manipulation at millimeter waves
In this work a methodology to shape the near field of radiating apertures is presented. The technique, despite being generic, is applied to the specific scenario of shaping the focal pattern of a 12λ focusing aperture at 30 GHz. The main result comprises the capability to shrink/enlarge the focal depth, without affecting the spot diameter. To verify the concept, the acquired aperture distribution is mapped on a Radial Line Slot Antenna (RLSA), which has been manufactured and measured, showing excellent results.
