摘要

摘要: 随着5G技术在煤矿的应用，多系统之间的信号干扰愈发密集，严重影响数据、语音和图像通信的质量，煤矿井下多系统共存问题日益凸显。针对该问题，设计了一种可同时工作于WiMAX/WiFi/4G/5G NR频段的矿用多频段微带天线。该天线在平面单极子天线的基础上，通过加载2个L形枝节及在地板上加载倒L形枝节的方式，使天线能够在多频段工作。仿真结果表明：该天线的中间、右侧和左侧枝节分别产生了2.4，3.5，4.8 GHz的谐振点，而在地板加载的倒L形枝节则提供了1.9 GHz的谐振点，天线可工作在3个频段，分别为1.88～2.73，3.26～3.79，4.7～5.9 GHz，能够有效覆盖WiMAX/WiFi/4G/5G NR煤矿井下全部的工作频段；由天线的峰值增益和归一化方向图可知，该天线在需要的工作频段内增益性能和整体辐射性能良好。

Abstract: With the application of 5G technology in the coal mine, the signal interference between multiple systems becomes more and more intensive. This seriously affects the quality of data, voice and image communication. The coexistence of multiple systems in coal mine becomes increasingly prominent. To solve this problem, a multi-band microstrip antenna for mine is designed, which can work in WiMAX/WiFi/4G/5G NR band at the same time. Based on a planar monopole antenna, the antenna can work in multiple frequency bands in the mode of loading two L-shaped branches and loading an inverted L-shaped branch on the floor. The simulation results show that the antenna's middle, right and left branches produce 2.4, 3.5 GHz and 4.8 GHz resonance points respectively. The inverted L-shaped branch loaded on the floor provides 1.9 GHz resonance point. The antenna can work in three frequency bands, which are 1.88-2.73, 3.26-3.79 GHz and 4.7-5.9 GHz respectively. The antenna can effectively cover all the operating frequency bands of WiMAX/WiFi/4G/5G NR in coal mines. According to the antenna's peak gain and normalized pattern, the antenna has good gain performance and overall radiation performance in the required operating frequency band.
