摘　　要：超宽带天线在矿井下应用发射和接收是有方向的,天线的尺寸要求小型化。首先对超宽带圆片单极天线和小型单极天线进行了分析,通过反射损耗的测量预仿真和方向图仿真,得到了2种天线的优点和不足,在此基础上,对小型单极天线进行了改进,并进行了方向图仿真,通过仿真可以看到,改进的天线更适合煤矿井下的通信要求。Ultra-wideband antenna applied in mine tunnels is transmitting and receiving directions. The antenna size requires miniaturization. First of all ultra-wideband monopole antenna and small wafer monopole antenna are analyzed by return loss measurement of pre-simulation and pattern simulation, the strengths and weaknesses of two antenna are acquired. On this basis, the small monopole antenna is improved, and simulated in direction map. The improved antenna is more suitable to coal mine communication requirements through simulation.
