Abstract

Transmission line theory for the impedances of wire antennas immersed in a cold magnetoplasma is proposed. The theory is applicable to antennas which are not necessarily small in terms of a wavelength measured along the antenna wire. The transmission line theory for the impedance of a very thin cylindrical dipole antenna leads to the Balmain quasi-static theory when the antenna length reduces to zero. New impedance resonances which would be observed for antennas of finite length in a magnetoplasma in the frequency region below and near the electron cyclotron frequency are predicted by the present theory.
