    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.
