本文介绍了一种基于液晶（LC）技术的可重构移相器，用于空间应用。讨论并详细描述了一种用于ka波段的可调谐移相器的性能和功能。这封信的重点是放在液晶在实验室模拟的空间辐射条件下的性能，包括表面充电、x射线和伽马辐射效应。测试结果表明，液晶对空间辐射环境的不利影响具有相当的弹性。
This letter presents a reconfigurable phase shifter based on liquid crystal (LC) technology for use in space applications. A tunable phase shifter for the Ka-band is discussed and described in detail in terms of performance and functionality. The focus of this letter is placed on the performance of liquid crystals in lab-simulated space radiation conditions including surface charging, X-ray, and gamma radiation effects. Test results suggest that liquid crystal is quite resilient to adverse effects from the space radiation environment.
