Abstract :The paper proposes and tests an effective method for improving the directivity of diffraction-type leaky-wave antennas based on the implementation of a longitudinal change in the profile of the distribution-radiating system due to the variation of the aiming distance according to a given amplitude distribution. It has been established that changing the aiming distance along the aperture according to a theoretically calculated regularity makes it possible to improve the initial directional properties of the antenna: to reduce the maximum level of side lobes, and also to increase the antenna gain.Keywords : microwave range, antenna array, side lobe level, gain, radiation patterns
