本文提出了冷磁等离子体中线天线阻抗的传输线理论。该理论可应用于就沿天线导线沿着测量的波长而言不一定小的天线。传输线理论的阻抗非常薄的圆柱形偶极子天线导致巴尔曼准静态理论时，天线长度减少到零。新的阻抗共振，这将是观察到的有限长的天线在磁等离子体中的频率区域低于和接近电子回旋频率的本理论预测。
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.
