Abstract
A reflection canceling element composed of a slot with inductive wall in the waveguide is proposed and analyzed. The frequency characteristics are calculated by the method of moments. Only the axial component of electric current along the waveguide height is assumed on the wall. The initial reflection of about -15 dB for isolated longitudinal slot is suppressed below -20 dB over 100 MHz by installing an inductive wall. The use of an inductive wall instead of post contributes to the simple fabrication of the reflection canceling element in single layer slotted waveguide arrays.
