摘　　要：为完善地球同步轨道(GEO)航天器静电放电(ESD)风险评估手段,文章根据空间ESD辐射电磁波频带特性,利用三维电磁场仿真软件ANSYSS HFSS,采用矩形贴片天线等效技术、梯形地平面技术和CPW馈线指数渐近线化技术开展航天器高压太阳电池阵列ESD检测用柔性天线传感器研究。采用聚酰亚胺(PI)作为柔性天线基底,其厚度为0.28 mm;柔性天线在弯曲半径分别为100、300、500 mm以及不弯曲条件下,300 MHz~2 GHz频带范围电压驻波比(VSWR)小于3,其中在650 MHz~2 GHz频段范围VSWR小于2。通过搭建的ESD模拟试验平台对传感器的电磁脉冲(EMP)信号检测性能进行实测分析,结果表明传感器能够有效地检测到高压太阳电池阵列表面的ESD EMP信号,具有用于航天器ESD故障预警的潜力。In order to improve the electrostatic discharge(ESD)risk assessment method for geosynchronous orbit(GEO)spacecraft,research on flexible antenna sensors for spacecraft ESD radiation detection were carried out in this article.Based on the frequency band characteristics of space ESD radiation electromagnetic wave,the means applied included the three-dimensional electromagnetic field simulation software ANSYSS HFSS,the equivalent technology of rectangular patch antenna,the trapezoidal ground plane technology and the CPW feeder exponential asymptotic technology.Polyimide(PI)was used as the base of the flexible antenna,and its thickness was 0.28 mm.The voltage standing wave ratio(VSWR)was less than 3 in the 300 MHz to 2 GHz frequency band range when the bending radius was 100,300,500 mm and no bending,of which the VSWR was less than 2 in the 650 MHz to 2 GHz frequency band range.The electromagnetic pulse(EMP)signal detection performance was measured and analyzed by the ESD simulation test platform.The results show that the designed antenna can detect ESD EMP signal effectively,with the potential to be used for spacecraft ESD fault warning.
