Abstract

The paper proposes a single antenna that can generate dual-mode plane spiral orbital angular momentum (PS-OAM) beams. Six Vivaldi antennas placed in a tangential circular array make up the antenna, and the antenna is etched onto a substrate material and has a flat design, allowing for easy integration with other system components. The neighbouring ports of the antenna elements have phase differences, so phase-shifting in the feeding network is unnecessary. When fed with the same phase and amplitude, the antenna can produce PS-OAM beams with mode +1 at 7 GHz and mode +2 at 14 GHz, and the measured purity is 80.6% and 63%, respectively. The method may provide a new way to produce multi-mode orbital angular momentum.

利用 Vivaldi 天线阵列生成双模 PS-OAM 波束
本文提出了一种可产生双模式平面螺旋角动量(PS-OAM)波束的单天线。六根维瓦尔第天线组成一个切向圆形阵列,天线蚀刻在基底材料上,采用扁平设计,便于与其他系统组件集成。天线元件的相邻端口具有相位差,因此无需在馈电网络中进行移相。当以相同的相位和振幅馈电时,该天线可产生 7 千兆赫模式+1 和 14 千兆赫模式+2 的 PS-OAM 波束,测得的纯度分别为 80.6% 和 63%。该方法为产生多模轨道角动量提供了一种新途径。

期刊介绍: Micro & Nano Letters offers express online publication of short research papers containing the latest advances in miniature and ultraminiature structures and systems. With an average of six weeks to decision, and publication online in advance of each issue, Micro & Nano Letters offers a rapid route for the international dissemination of high quality research findings from both the micro and nano communities. Scope Micro & Nano Letters offers express online publication of short research papers containing the latest advances in micro and nano-scale science, engineering and technology, with at least one dimension ranging from micrometers to nanometers. Micro & Nano Letters offers readers high-quality original research from both the micro and nano communities, and the materials and devices communities. Bridging this gap between materials science and micro and nano-scale devices, Micro & Nano Letters addresses issues in the disciplines of engineering, physical, chemical, and biological science. It places particular emphasis on cross-disciplinary activities and applications. Typical topics include: Micro and nanostructures for the device communities MEMS and NEMS Modelling, simulation and realisation of micro and nanoscale structures, devices and systems, with comparisons to experimental data Synthesis and processing Micro and nano-photonics Molecular machines, circuits and self-assembly Organic and inorganic micro and nanostructures Micro and nano-fluidics
