A study is made of the electrodynamic characteristics of an antenna having the form of an infinitesimally thin, perfectly conducting narrow strip located at the plane interface of a uniaxial magnetic metamaterial and an isotropic magnetodielectric medium. The antenna is perpendicular to the anisotropy axis of the metamaterial and is excited by a time-harmonic given voltage. Singular integral equations for the antenna current are obtained in the case of an infinitely long strip conductor. Based on the solution of these equations, the current distribution and input impedance of the antenna are found and analyzed. The limits of applicability of an approximate method based on the transmission line theory for determining the antenna characteristics are established. Within the framework of this method, the results obtained are generalized to the case of a finite-length strip antenna.
