Study of Down-hole Interphone Loop Antenna Transmitting Distance Based on Electro-Magnetic Field Theory
You Li-yan · 2007
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.
