Abstract
A new techique is proposed for suppressing sidelobes due to the wave reflected from the waveguide end in the traveling-wave slot array. In this approach we use multiple sections of reduced-height waveguide with the final section terminated with a short circuit instead of the conventional matched load. To show the validity of the proposed method, a Ku-band slotted waveguide is fabricated and tested. Measurements confirm the excellent sidelobe suppressing capability of the proposed method.
