| 摘 要： | 在UWB通信中，利用赫兹磁偶极子天线的微分特性，由输入方波的上升沿产生窄脉冲。对不同尺寸的赫兹磁偶极子天线的发射信号进行了测试及分析，由测试结果表明，该天线作为发射天线具有良好的微分特性，实现了宽带辐射。天线的尺寸对发射脉冲的宽度和幅度有较大的影响，天线的尺寸越大，其辐射的脉冲信号幅度越高，但其脉冲宽度也越宽。

| Abstract: | For a UWB communication system, by using differential characteristic of Herz magnetic dipole antenna, the narrow pulse can be produced from the rise edge of input square-wave signal. In this paper, the emitting signals of Herz dipoles with different dimension are tested and analyzed. The measured results show the width and attitude of the emitting pulse depends on the dimensions of dipole, the larger of the Herz dipole's dimension, the higher of the emitting signal attitude and the wider of the emitting pulse width. |
