摘　　要：井下对讲机的环天线发射距离远近与天线的效率有关。基于电磁场理论对环天线电磁辐射场辐射功率的分析和集肤与邻近效应的分析,设计井下对讲机时应该采用增加天线匝数和加粗天线半径的方法来提高其的发射距离。The loop antenna on down-hole interphone was designed and the conclusion was drawn that adding turn and radius of antenna can enhance the transmitting distance of antenna though the analysis of electro-magnetic field, the skin effect and proximity effect, since the transmitting distance is concerned with the efficiency of the loop antenna on down-hole interphone.
