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:根據縫隙口面切向場的連續條件，採用解析數值法矩量法，對扇面波導寬壁上窄的斜縫進行了計算，解得了磁流系數及其分佈，並得到散射場、等效散射參量及等效阻抗等重要參數.假定波導中僅有te11主模傳輸，在x波段計算了散射參量和歸一化等效串聯阻抗，給出計算結果，為縫隙天線和縫隙陣列設計提供了依據 -
