摘　　要：设计了一种火山烟雾形平面印刷超宽带天线.研究显示其阻抗带宽低频端可达0.8GHz,在加载电阻回路后带宽低频端可扩展至0.5GHz,在1ns宽的高斯微分脉冲激励下,双锥天线作为发射天线,比较了加载电阻和未加载电阻天线的接收波形,由结果可知,加载天线可以进一步减小脉冲信号波形失真。A plane volcano smoke antenna is designed,It is found that its lower cut-off frequency of the antenna will be 0.8GHz.The lower cut-off frequency may be down to 0.5GHz when the antenna is loaded resistance loop circuits.The receiving waveforms of loaded antenna and non-loaded antenna are compared each other when a bi-conical antenna is used as transmitting antenna and is fed by 1ns Gauss differential pulse.The result indicates that the loaded antenna can reduce the waveform distortion.
