摘　　要：对用负阻抗变换电路同圆锥螺旋天线相结合，构成的有源接收天线进行了理论分析。并给出了该有源天线稳定工作的条件和设计原理。结果表明，用该方法设计的有源接收天线具有很宽的频带、较高的灵敏度和很小的尺寸，是多频电磁波测井较为理想的接收天线。An active receiving antenna consisting of conical helix antenna and a negative impedance changing circuit is analyzed in this paper.The stable operating condition and designed principle of the active receiving antenna are also given.The analysis shows that the active receiving antenna designed by this method has wider band and higher sensibility and small size.It is a better receiving antenna for multi-frequency electromagnetic wave log.
