The radiation pattern in the near and far field of each frequency component of the spectrum of current pulse on a transmission line.
传输线线上脉波电流之频谱与分布及其各频率成份之辐射远近场型之差异。

The time-domain pulse antenna has the ability to radiate and receive the fast changed transient signal, because this kind of pulseradiation antenna has very wide frequency range.
时域脉冲天线具有辐射和接收快速变化的瞬态脉冲信号的能力，这种脉冲天线能够覆盖很宽的频带。

The studies have found that the radiationpulse will be broadened after passing through the UWB antenna, and the spectrum will shift entirely to the lower frequency band.
