ABSTRACT

An approximate analytical solution of the problem on the current distribution along the uncoupled linear impedance antenna in the circular waveguide under arbitrary conditions of antenna excitation and orientation is found using the method of averaging. The relationship between the symmetric and antisymmetric components of the current is taken into account in a single form for both the resonance and nonresonance events. The expression for the characteristic antenna resistance is obtained and dispersion equation for the antenna is found. The results of current calculation and the numerical and experimental values of the resonance frequency of the antenna are given.
