1. Abstract : according to the continuative condition of the tangential fields on the slot aperture which is the inclined narrow - slot on the broadwall of a sectoral waveguide , the moment method is used to calculate the magnetic current coefficient and distribution . then the scattering field , the scattering parameter and the equivalent impedance are obtained . leting only the te11 dominant mode propagates in the waveguide , the scattering parameters and the normalized equivalent series impedance in the x - band are computed . the basis disigned the slot antenna and the slot array is offered
   文摘:根據(jù)縫隙口面切向場的連續(xù)條件，采用解析數(shù)值法矩量法，對扇面波導(dǎo)寬壁上窄的斜縫進行了計算，解得了磁流系數(shù)及其分布，并得到散射場、等效散射參量及等效阻抗等重要參數(shù).假定波導(dǎo)中僅有te11主模傳輸，在x波段計算了散射參量和歸一化等效串聯(lián)阻抗，給出計算結(jié)果，為縫隙天線和縫隙陣列設(shè)計提供了依據(jù)
