摘要: 本文分析了圓波導(dǎo)中同心螺旋線內(nèi)外的圓電波H○01、H◎01之間的耦合系數(shù),指出了文獻(xiàn)[1]關(guān)于H○01H○02模式變換器設(shè)計(jì)中的不妥之處。給出了較完整的設(shè)計(jì)公式。實(shí)驗(yàn)證實(shí)了本文的理論分析是正確的。在3237.5 GHz頻率范圍內(nèi),變換損耗低于0.6 dB,雜模(H○01)幅度低于15 dB,輸入駐波比低于1.2。

Abstract: The coupling coefficient between circular-electric modes H○01 and H◎01 through a spiral line in circular waveguide is calculated. Certain corrections to S. E. Miller s design of a H○01H○02mode transducer are made. More complete design formulas are given. Agreement between experimental results and our theoretical calculations is attained. In the frequency range from 32 to 37.5 GHz, the conversion loss is less than 0.6 dB, the amplitude of unwanted mode (H○01) less than15 dB and the V. S. W. E less than 1.2. -
