摘　　要：为确保航天环境下载体内的微带天线性能满足通信系统要求,采用多层和多模技术设计了单开槽WiFi频段的宽带微带天线,重点对载体及环境因素下宽带微带天线的性能进行仿真验证,同时分析了对天线性能的影响,并采用迭代补偿方法进行了性能修正。仿真分析结果表明:提出的迭代补偿方法对微带天线性能可以进行有效的校正;实物验证结果表明:载体内的微带天线性能稳定,满足工作频带要求。To ensure that the performance of microstrip antennas in the space environment could meet the requirements of the communication systems,a single slot microstrip antenna with operating WiFi frequency band was designed using multi⁃layer and multi⁃mode technology.The performance of the microstrip antenna based on the carrier environmental factors was simulated and verified,and the influence on microstrip antenna performance was analyzed.In addition,performance correction was carried out using iterative compensation methods.The verification results showed that the iterative compensation method could correct the performance of the microstrip antenna,ensuring the stable working performance of the microstrip antenna on the carrier environment and meeting the require⁃ments of the working frequency band.
