SINOPSIS

The problem of radiation of a non-symmetrical cylindrical vibrator of an arbitrary radius upon axially symmetric excitation is investigated by a rigorous method. The ground of the suggested approach is a representation of surface currents flowing on the vibrator as an expansion in basic functions of subdomains on the vibrator surface. The solution of the mentioned problem is reduced to an infinite set of algebraic equations for unknown coefficients of the current expansion with a matrix consisting of generalized impedances and voltage vector in a right part of the system. The currents flowing on the cylindrical surface were calculated and the comparison of results obtained with known ones was carried out. The formula for field calculation in far-field zone and the dependences of antenna input impedance versus frequency are given as well.
