摘要:

针对外场电磁兼容性试验天线性能受温度影响导致测试结果产生误差的问题,以电磁兼容辐射发射测试中常用的有源单极振子天线为研究对象,分析了温度变化对天线接收性能的影响机理,提出了一种基于温度效应的天线接收特性测试方法, 获得了典型天线接收特性随温度的变化规律及天线系数误差修正曲线,用于外场自然温度环境下测试结果误差修正。结果表明,典型有源单极振子天线在?40℃至50℃温度范围内最大接收误差可达5 dB,通过误差修正可以扩展天线的使用范围,还可为同类天线的外场使用提供参考。

Abstract:

To solve the problem that the performance of the antenna in out-field electromagnetic compatibility (EMC) test is affected by the temperature, which leads to the error of the test results, taking the active monopole antenna commonly used in the EMC radiated emission test as the research object, the influence mechanism of the temperature change on the receiving performance of the antenna is analyzed, and a temperature-effect-based testing method for antenna receiving characteristics is proposed. The variation pattern of typical antenna receiving characteristics with temperature and the antenna coefficient error correction curve are obtained for error correction of test results in out-field natural temperature environments. The results show that the maximum receiving error of a typical active monopole antenna can reach 5 dB within the temperature range of ?40°C to 50°C. Through error correction, not only the usage range of the antenna can be extended, but it can also provide a reference for the out-field use of similar antennas.

Key words: electromagnetic compatibility, radiated emission, antenna factor, temperature
