Abstract

In this letter, an analytical method for studying the theory of an arbitrarily oriented multifeed very low frequency linear antenna in a cold magnetoplasma is proposed. The node currents and admittances are calculated by solving the matrix equation. Analysis and computations show that the current concentrates on multiple feed points, and amplitudes will decrease when the dip angle rises. It is also found that both the self- and mutual admittances will decrease in general with the increase of the dip angle and the electrical length, respectively. The approach can provide theoretical assistance and technical guidance for practical spaceborne multifeed antennas in the near future.

冷磁等离子体中任意取向多馈源线性天线理论

本文提出了一种研究冷磁等离子体中任意取向多馈入极低频线性天线理论的解析方法。通过求解矩阵方程计算节点电流和导纳。分析和计算表明，电流集中在多个进给点上，且振幅随倾角的增大而减小。自导纳和互导纳随倾角的增大而减小，随电长度的增大而减小。该方法可为将来实际的星载多馈天线设计提供理论支持和技术指导。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
