摘要
给出一个单连通的空间电流线圈在远区辐射的时域电磁场，应用等效性原理和场的迭加性，求出圆柱螺旋天线的辐射场分布。
In this paper, the analytic expressions of electromagnetic fields in the far zone produced by a single transient current traveling along a filamentary loop are derived in the time domain.By the equivalent principle and the fields superposition, the radiation characteristics of circular helix antennas are given.
