| 摘 要： | 对于井下中频便携式发射机所使用的天线,不能使用评价地面上天线性能的指标来评价其性能。通过对鞭状天线和环状天线的比较指出:鞭状天线不适宜于井下中频便携式发射机,而环状天线则是井下中频便携式发射机可使用的较好的天线型式。

| Abstract: | Studying the transmit antennas used in the underground medium frequency portable transmitters, the authers point out that many quantities defined to evaluate the antennas in air can not be used to evaluate the antennas of the underground MF portable transmitters. After comparing a whip antenna with a loop antenna, the authers notice that the whip antenna is not suitable for the underground MF portable transmitters while the loop antenna is the better antenna used for them |
