摘要：

Through theoretical analysis of the coaxial cable used in mine 5G (5th-Generation) communication base station theoretically, a radio frequency energy loss model and an optimization method were proposed. The inherent attenuation and loss caused by impedance mismatch of 5G communication coaxial cable were quantitatively analyzed. In addition, combined with characteristics of mine tunnels as well as influence of base station and antenna positions on 5G signal transmission loss, a geometric relation of coaxial cable angles was established and an optimization model of radio frequency energy loss in mining 5G communication system was deduced. According to above-mentioned attenuation model and optimization method, it can be seen that the optimal angle of minimum impedance mismatch loss is 106.5° and the length of coaxial cable is 0.42 m. It can be seen from the experimental comparison and judgment with the commonly used values in the project, the optimized values of radio frequency signal strength and the transmission rate optimization value indexes increase respectively, which provides technical supports for the construction of mine 5G communication system and intelligent mine. © 2021, Editorial Board of Journal of Huazhong University of Science and Technology.
