摘要: 該文詳細(xì)推導(dǎo)了用電、磁偶極矩展開表示的電小尺寸輻射體在 GTEM室的輻射功率與開闊場(chǎng)中輻射場(chǎng)之間的理論關(guān)系,修正了 Lee理論中相應(yīng)公式,并將理論結(jié)果與標(biāo)準(zhǔn)單極子輻射源實(shí)驗(yàn)結(jié)果進(jìn)行了比較。結(jié)果表明兩者符合的很好。這說(shuō)明 GTEM室和開闊場(chǎng)輻射測(cè)量具有密切的相關(guān)性。對(duì)于電小尺寸的輻射體,GTEM室不僅可以用于 EMS測(cè)試,也可用于做 EMI測(cè)試。

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. -
