摘　　要：本文对磁感应透地通信发射天线的物理尺寸和材料展开了研究,首先建立了磁感应透地通信系统模型,基于该模型得出影响磁感应透地通信系统传输距离的因素并确定了环天线的物理参数,然后采用有限元软件对相同物理参数的高温超导环天线和铜环天线进行建模与损耗分析。仿真结果表明,同一周期下高温超导环天线的损耗为1.32488*10^(-5)J,而铜环天线的损耗为7.639 J,得出高温超导环天线在降低热损耗方面有着明显的优势。In this paper,the physical size and materials of the transmitting antenna for magnetic induction ground penetrating(MICP)communication were studied.Firstly,a MICP communication system model was established.Based on the model,the factors to affect the transmission distance of the MIGP communication system were obtained and the physical parameters of the ring antenna were determined.Then,the finite element software was used to model and analyze the losses of high temperaure superconducting(HTS)and Cu ring antennas with the same physical parameters.The simulation results show that the loss of the HTS antenna is 1.32488*10^(-5) J,while the loss of the copper antenna is 7.639 J.The results show that the HTS antenna has obvious advantages in reducing the heat loss.
