As a one-time miniaturized device used to generate and radiate electromagnetic pulse,the radio frequency explo-sive magnetic flux compression generator (RF MFCG) still has the bottle-neck in application because of the structure and proper-ties of its radiation antenna.In order to solve this problem,the mechanism that the RF MFCG generates and radiates electromag-netic pulse is studied first in this paper.Then an RF MFCG miniaturization conformal antenna suitable for the actual demand is put forward on this basis.The antenna is designed to be a part of the body of the magnetic flux compression generator,which en-sures the miniaturization and practicability of the device in terms of structure.The results of CST simulation and physical test show that the conformal antenna has good radiation characteristics in the frequency band of 0.5 GHz to 10.3 GHz,and it also can meet the practical demand of the RF MFCG in radiation performance.%射频爆磁压缩发生器作为一次性电磁脉冲产生和辐射的小型化装置,其辐射天线的结构和性能是其在实用化层面亟待突破的瓶颈.针对这一问题,深入研究了射频爆磁压缩发生器产生和辐射电磁脉冲的机理,并在此基础上,提出了一种适于实际需求的射频爆磁压缩发生器小型化共形天线.此共形天线设计成爆磁压缩发生器本体的一部分,在结构方面保证了该装置的小型化和实用性.CST仿真和实物测试结果表明,此共形天线在0.5 GHz到10.3 GHz的频带上具有良好的辐射特性,在辐射性能方面同样可以满足射频爆磁压缩发生器实用性的需求.
