| 摘 要： | 从一个新的设计思想出发，对地下钻孔中的宽带发射天线进行了探索，获得了一种新颖的柱形宽带天线形式。设计制作了这一种天线，进行了相应的分析和实验。通过现场测试，证明该天线的工作频带至少可达５个倍频程（５．９～３０．９ＭＨｚ），可用以代替目前无透设备中所用的半波振子天线，并达到或超过半波天线的探测距离，是一种新型的宽带发射天线，有极好的应用前景。

| Abstract: | This paper presents a new design procedure and obtains a new cylinder broadband Antenna. This antenna is designed and is made while an experiment is carried out. The given testing results show thatthe frequency range is from 5.9 MHz to 30.9 MHz and may be used instead of half-wave doublet antenna.This antenna has a broad prcopect. |
