| 为兼容全球主流卫星导航系统，顺应小型化、低成本发展趋势，设计了一种兼具轻质、小型化、宽频带、高增益等优点的可展开GNSS-R天线。该天线通过组阵使用，展宽波束覆盖范围并提高增益；螺旋线采用柔性支撑和固定支撑相结合的形式，引入收拢固定装置和解锁装置实现收拢与展开。通过与传统螺旋天线对比，从结构设计和力学仿真角度阐述了可展开GNSS-R天线方案的可行性，该天线既具有可展开天线收拢尺寸小、重量轻的特点，又具有传统天线结构稳定的特点。 |

| Abstract: |
| To be compatible with mainstream global satellite navigation systems and align with the trend of miniaturization and low-cost, a deployable GNSS-R antenna which combines the advantages of light-weight, compact-size, broadband and high-gain has been designed. By operating in an array configuration, this antenna can broaden the frequency band as well as increase gain; the helix adopts a combination of flexible and rigid supports; the antenna utilizes stowing/locking mechanisms and unlocking mechanisms to achieve compact storage and reliable deployment. Compared with traditional spiral antennas, the feasibility of the deployable GNSS-R antenna solution is demonstrated from perspectives of structure design and mechanical simulation. This antenna has both the compact stowed size, light-weight characteristic of deployable antennas and the structural stability of traditional antennas. |
