摘要

在这项工作中,我们全面回顾了有限孔径一维漏波天线(LWAs)波束宽度评估的最新进展。事实上,一维光阱的光束特性通常是在无限孔径下评估的,直到最近才考虑到孔径截断的影响。然而,孔径截断对一维单向光路的影响与对端射一维光路的影响不同,对一维双向光路的影响更大。每一种情况都值得单独分析,本文提供了评价这种效果的一般公式。

New Beamwidth Formulas for 1-D Leaky-wave Antennas: A Review
In this work, we comprehensively review the recent developments made in the context of the beamwidth evaluation in finite-aperture one-dimensional (1-D) leaky-wave antennas (LWAs). Indeed, the beam properties of 1-D LWAs are commonly evaluated assuming an infinite aperture, and only very recently the effect of the aperture truncation has been accounted for. However, the effects of the aperture truncation on 1-D unidirectional LWAs are different from those on endfire 1-D LWAs, and even more different from those on 1-D bidirectional LWAs. Each case deserves its own analysis, and this paper provides general formulas for the evaluation of such effects.
