摘要
用矩量法得到螺旋天线的电流分布,并在此基础上进一步确定了螺旋天线的近场分布。提出了用来度量线天线近场耦合强度的一种方法。针对螺旋天线的近场计算并描绘出了耦合度随收发间距变化的曲线图。
MoM is used to analyze current distribution on helical radiator, and then ascertain its near-field distribution. Based on above work, a trial method in order to measure the couple intensity of thin linear antenna's near field is put forward. In the end, a curve graph of the couple intensity which is the dependent variable of the distance between the helical antenna and the receiving antenna is computed and painted.
