Abstract高增益、低剖面、低质量的平面反射阵天线广泛应用于卫星通信及空间探测领域.目前虽有多种新型星载反射阵天线设计,但尚未大规模实际应用.反射阵天线在加工、组装过程中出现的误差以及在空间高低温环境中产生的形变误差都会对其电特性产生影响.为验证反射阵天线大规模实际应用于空间探测的可行性,研究了反射阵天线可能出现的形变误差对其辐射特性的影响,从理论上分析了反射阵单元发生位移、旋转、变形时反射相位的变化规律,并且从反射阵天线设计实例出发,利用科学计算和电磁仿真软件对天线的方向图、增益等特性进行仿真分析,研究形变对反射阵天线电性能的影响.
Other AbstractReflectarray,combined the features of reflector and array antenna,has been developed rapidly in last several decades and has been used in many applications.High-gain,low-profile and low-weight planar reflectarray antenna can be widely used in space area.Though several novel reflectarray antennas such as metal-only reflectarray,inflatable reflectarray and transparent reflectarray are designed for space use,the massive applications of reflectarray in space area are not realistic due to the reliability requirements.The fabrication error,assembling error and the heat deformation in high and low temperature will affect the electrical performance of the antenna dramatically.To analyze the changing of the radiation properties resulted from deformation in real environment,the theoretical analysis of the reflection phase for element vertical and horizontal displacement and deformation are carried out.Then two reflectarray antennas with different aperture sizes are designed to find the overall influence of deformation.Scientific calculation with MATLAB and electromagnetic simulation with HFSS are adopted to verify the analysis.The radiation patterns and gain performances of the two reflectarray antennas under several different conditions such as rotation,inverted V-shape deformation and irregular deformation are compared and summarized.The precautions against deformation are also given.
