摘要
天线时域近场测试技术是一种新兴、高效的天线测试技术,能够快速精确地测量出天线的时域场和宽带特性。目前我们已成功组建了国内第一套天线时域平面近场测试实验系统,并对L、S、C、X四个波段的标准天线方向图进行了验证测试,把测试结果跟频域近、远场测试系统上测得的结果进行比较,证明时域近场测试理论的正确性和测试系统的实用性。本文对这套系统的组成结构和天线的测试结果进行说明分析。
Antenna time-domain near-field measurement technology is a new, efficacious antenna measurement technology, which can obtain antenna＇s time-domain and broad-band radiation characteristic rapidly and accurately. Now we have successfully founded the first antenna time-domain near-field measurement system in China. The paper presents the components of the system and the results of the demonstration measurement. The results show the validity and feasibility of the theory and the measurement system.
