摘要: 该文详细推导了用电、磁偶极矩展开表示的电小尺寸辐射体在 GTEM室的辐射功率与开阔场中辐射场之间的理论关系,修正了 Lee理论中相应公式,并将理论结果与标准单极子辐射源实验结果进行了比较。结果表明两者符合的很好。这说明 GTEM室和开阔场辐射测量具有密切的相关性。对于电小尺寸的辐射体,GTEM室不仅可以用于 EMS测试,也可用于做 EMI测试。

Abstract: This paper derives in detail the horizontal radiated electric fields from an elec-trically small radiator which may be well represented by the electric dipole and the magnetic moments, then the Lees corresponding formula are modified. Theoretical results compared with experimental data measured directly over OATS agree well. This shows that GTEM cell measurements are correlative with OATS emission measurements. For the electrically small radiator, GTEM cell may be used not only for EMS test but also for EMI test. -
