Goal of investigation - designing and more accurate definition of calculation method, mathematical models and software for calculating the characteristics of linear, curve, longitudinal homogeneous and inhomogeneous slots and array of their. Technique of investigation - theoretical researches, computer analysis , experiment. The waveguide -slot array of corner form was proposed. For such systems the approximate mathematical model and optimization technique was worked out. The mathematical model of the nonregular trapezium form slot exited by the base mode of the recfaugular waveguide was worked out. The mathematical model of the in homogeneous waveguide slot radiator of leaky wave was worked out. The inhomogeneous vibrator-and-slot radiator providing the symmetrical and weakly directional pattern and circular or operated polarization was proposed. The experimental specimen of such antenna was designed and possibility of the variation of its electrodynamic characteristics was shown.
