| 摘 要： | 根据缝隙口面切向场的连续条件,采用解析数值法--矩量法,对扇面波导宽壁上窄的斜缝进行了计算,解得了磁流系数及其分布,并得到散射场、等效散射参量及等效阻抗等重要参数.假定波导中仅有TE-11主模传输,在X波段计算了散射参量和归一化等效串联阻抗,给出计算结果,为缝隙天线和缝隙阵列设计提供了依据. |

| 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 TE 11 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. |
| Keywords: | waveguide slot antennas electromagnetic fields radiation sectoral waveguide scattering parameter |
