Abstract
Problems of the statistical synthesis of a linear continuous antenna in order to obtain maxima of its mean directivity and mean gain are considered. A technique of these problems solution is given. Its core is in the allowance for random errors in the antenna at the initial stage of synthesis problems solution, leading to significant suppression of the superdirectivity (SD). Plots illustrating a degree of SD suppression versus errors parameters, the ohm losses and antenna sizes are presented.
KEY WORDS: antenna pattern, superconductivity, super-directivity
