Abstract
This paper presents a non-periodic grating technique to reduce the sidelobe levels of radiation from a reflector antenna. In particular, the theoretic foundation is developed in this paper to examine the possibility of using the grating screen to reduce the sidelobe levels. The grating screens are placed over the reflector's aperture so that it can eliminate the waves that are negative to the sidelobe suppression. Theoretic formulation as well as demonstrating examples will be presented to validate the feasibility.
