Suppression of the slot-mode radiation in a slitted waveguide using periodic slot perturbations
Abstract
Transverse perturbations in the form of periodic slots in the narrow-wall are employed to suppress the slot-mode radiation in a slitted waveguide. The presence of the perturbations alters the fast wave supported in an unperturbed slot to a slow wave. Slitted waveguides with and without perturbations were compared in full-wave simulations and in measurements. It will be shown that significant and consistent reduction of the slot-mode radiation is achieved with the perturbations. © 2009 IEEE.
