| Abstract: | In view of the problem of the complexity and difficult forecast on wireless underground communication, a wave propagation model is established for the loop antenna in the underground communication in this paper. Performance of the magnetic antenna and electrical antenna is compared, and the desired transmitting power in a given condition and factors affecting the communication are analyzed, thereby selecting the optimal operating frequency to achieve communication optimization. It has very important guiding significance for engineering practice. |

| Keywords: | underground communication loop antenna electromagnetic field transmitting power optimal operating frequency |
