通过巷道电磁波传输损耗公式分析了矿井中影响传输损耗的三个因素。以工作频率为为2.45GHz的RFID微带天线为实例,借助仿真软件HFSS和MATLAB得出影响传输距离的主要因素是巷道的倾斜角度。
The three factors affecting the transmission loss in mine are analyzed through the formula of transmission loss of roadway electromagnetic wave. Take the RFID microstrip antenna with working frequency of 2.45GHz as an example, the main factors influencing the transmission distance with the help of HFSS and MATLAB are the inclination of the roadway.
