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.
