Abstract

This study presents a new conformal antenna composite structure (CACS) based on damage tolerance for satellite navigation systems. In the CACS, a circularly polarized stacked microstrip antenna is embedded into a composite sandwich structure. Initial debonding defects are introduced between the radiating element and the other layers, in the manufacturing process, to avoid direct coverage of the radiating elements by the adhesive. The test results demonstrate that the CACS functions efficiently at the design operating frequencies, its bearing capacity well satisfies the design requirement, and it receives sufficient navigation satellite signals stably for precise positioning.

摘要

本研究提出了一种基于卫星导航系统损伤容限的新型共形天线复合结构 (CACS)。在 CACS 中，圆极化堆叠微带天线嵌入复合夹层结构中。在制造过程中，在辐射元件和其​​他层之间引入初始脱粘缺陷，以避免粘合剂直接覆盖辐射元件。测试结果表明，CACS在设计工作频率下高效运行，承载能力满足设计要求，稳定接收充足的导航卫星信号，实现精准定位。
