Abstract
It has been found experimentally that the efficiency of radiation of the slot mode in slotted waveguide antennas increases with the slot width. The excitation of the slot mode can be prevented by covering the slot with a thin film of metal. Alternatively, the slot may be covered with a sheet of dielectric to suppress the slot mode.
