摘　　要：电容负载螺旋型爆磁压缩发生器作为一种小型化电磁脉冲产生与辐射装置广泛应用于军事及科研的各个领域。辐射特性是衡量其性能的最主要参数之一。根据电小环天线等效原理,将装置定子线圈等效为电小环天线进行仿真研究,分析装置的辐射性能。给出了辐射电阻表达式。提出对装置加载辐射天线以提高其辐射效率。仿真分析表明加载鞭天线后可以有效改善装置辐射性能,所加载天线越长,直至与辐射波长可比拟,辐射效果改善越明显。Helix magnetic flux compression generator with loading capacitance is called radio frequencies explosive magnetic flux compression generator（RF MFC）,uses capacitors as the load is a kind of maneuverable device for generating and radiating electromagnetic pulse.Radiation performance is the key factor which determines system＇s performance.The radiation performance of RF MFCG is discussed which based on small loop antenna theory.The way to improve radiation performance is given.Whip antenna could be used as RF MFCG radiating antenna.This method has been proved in simulations.The longer antenna is,the better radiation performance will be until it could compare with the system wave length.
