摘　　要：双锥天线常使用于高功率电磁脉冲辐射中。本文采用基于时域有限积分法的数值仿真软件CSTMicrowave Studio对非对称双锥天线进行了辐射特性的研究,分别通过改变双锥天线一端的锥角,双锥天线的一端锥长等参数,研究双锥天线的辐射特性与锥长和锥角变化的关系,总结了一般的变化规律;然后对传统的同轴双锥天线进行研究,提出一种内外锥不等长的同轴双锥天线;最后设计一种同轴双锥天线,该天线具有很好的阻抗带宽和较高的能量辐射效率,同时具有辐射波瓣宽度窄,增益高的特点,适合用于要求增益高的脉冲信号辐射的场合。Biconical Antenna is usually used in radiation of High power electromagnetic pulse signal. By means of the CST Microwave Studio＊ EM simulation technology based on the Finite Integral Time-domain method, the character of asymmetric biconical antenna is studied. The influence to the radiative character of hiconical antenna by changing one side cone angle and one side cone length is given. Then coaxial biconical antenna is studied, a unequal length coaxial biconical antenna is put forward. An antenna is given in the end, the antenna has large bandwidth and good energy radiated rate,narrow radiative lobe and high gain. It can be used in the radiation of high gain pulse signal.
