Abstract: The ways to reduce the level of side lobes in slot antenna arrays are considered. A method is proposed to reduce the level of side lobes using two or more resonant waveguide-slot antenna arrays. The number of antenna arrays must be even and one should be shifted relatively to the other in space by the size of the gap step, so that the gap of the opposite slope is one above the other, due to this, the parasitic transverse component of the vector E is compensated. As a result, the level of the side diffraction lobes decreases by several orders of magnitude.
Keywords: antenna array, resonant waveguide-slot antenna array, radiation pattern
