本文提出了刚-柔天线阵（RFAA），这是一种用于实现超轻柔性天线阵的概念，该天线阵可以容易地集成有源元件。这使得能够实现可以紧凑地装载在小型卫星中的相控阵列，其中天线有效载荷的质量和体积极其有限。RFAA由非常薄的物理柔性材料和最小刚性材料构成，使其能够以低至1.1 $mathrm{k}mathrm{g}/mathrm{m}^{2}$的面密度实现。它采用了一种紧凑的新型电容天线馈电，简化了其结构。通过两个RFAA元件设计的仿真和两个原型阵列的测量，验证了这一概念。
this paper presents the Rigid-Flexible Antenna Array (RFAA), a concept for realizing ultra-light flexible antenna arrays that can readily integrate active components. This enables realization of phased arrays that can be compactly stowed in small satellites, where mass and volume for antenna payloads are extremely limited. The RFAA is constructed with a very thin, physically flexible material and minimal rigid material, allowing it to be realized with an area density as low as 1.1 $mathrm{k}mathrm{g}/mathrm{m}^{2}$. It employs a compact novel capacitive antenna feed, which simplifies its construction. The concept is validated through simulation of two RFAA element designs, and measurements of two prototype arrays.
