Abstract

We explore the use of a new modulated metasurface (MTS) antenna topology as solution for wireless backhaul at K band. The proposed structure is composed of a quasi-optical beamformer, which feeds the modulated MTS radiating aperture. These two elements are vertically stacked in a two-layer pillbox architecture to produce a very compact antenna. Furthermore, our design is able to provide several beams at different pointing angles and, hence, it offers the possibility of discrete beam steering by beam switching. The employment of a modulated MTS and the compactness given by the pillbox approach lead to a high-gain and low-profile antenna that could be an appealing solution for mobile backhaul networks.

用于K波段5G回程应用的多波束调制元表面天线

我们探索使用一种新的调制超表面（MTS）天线拓扑结构作为K波段无线回程的解决方案。所提出的结构由一个准光学波束形成器组成，该波束形成器向调制的MTS辐射孔径馈电。这两个元件垂直堆叠在两层碉堡结构中，以产生非常紧凑的天线。此外，我们的设计能够提供不同指向角度的多个波束，因此，它提供了通过波束切换进行离散波束控制的可能性。调制MTS的使用和碉堡方法提供的紧凑性导致了高增益和低轮廓天线，这可能是移动回程网络的一个有吸引力的解决方案。

期刊介绍： The Comptes Rendus - Physique are an open acess and peer-reviewed electronic scientific journal publishing original research article. It is one of seven journals published by the Académie des sciences. Its objective is to enable researchers to quickly share their work with the international scientific community. The Comptes Rendus - Physique also publish journal articles, thematic issues and articles on the history of the Académie des sciences and its current scientific activity. From 2020 onwards, the journal''s policy is based on a diamond open access model: no fees are charged to authors to publish or to readers to access articles. Thus, articles are accessible immediately, free of charge and permanently after publication. The Comptes Rendus - Physique (8 issues per year) cover all fields of physics and astrophysics and propose dossiers. Thanks to this formula, readers of physics and astrophysics will find, in each issue, the presentation of a subject in particularly rapid development. The authors are chosen from among the most active researchers in the field and each file is coordinated by a guest editor, ensuring that the most recent and significant results are taken into account. In order to preserve the historical purpose of the Comptes Rendus, these issues also leave room for the usual notes and clarifications. The articles are written mainly in English.
