摘要

提出了一种基于Miura-Ori图案的折纸反射单元格。这种折纸单元格允许有效的折叠/展开，高包装效率和易于部署。单元格由4个平行四边形块组成，可实现560°相移。对20 × 20元的Miura-Ori反射天线进行了优化设计，使其在8.425 GHz频率下向θ=20°和φ=0°方向辐射光束。最大实现增益为26 dBi。所提出的天线的主要优点是它能够在完全折叠状态下有效地包装自己，比完全展开状态下的天线占用的体积小4到5倍。这对小型卫星应用非常重要。

A Deployable and Reconfigurable Origami Reflectarray Based on the Miura-Ori Pattern

This paper presents a novel origami reflectarray unit-cell based on the Miura-Ori pattern. This origami unit-cell allows for efficient folding/unfolding, high packing efficiency and easy deployment. The unit-cell is composed of 4 parallelogram patches that can achieve 560° phase shift. A 20 × 20 element Miura-Ori reflectarray is optimized and designed to radiate a beam toward direction θ=20° and φ=0° at 8.425 GHz. A maximum realized gain of 26 dBi is obtained. The proposed antenna's main advantage is its ability to efficiently pack itself at its fully folded state to occupy 4 to 5 times smaller volume than the one at its fully deployed state. This is very important for small satellite applications.
