随着无线通信技术、射频技术、嵌入式等技术的飞速发展，无线通讯设备和系统凭借其灵活性强的优势越来越多地应用到农业中。无线信号在传播过程中会由于障碍物的存在而发生反射、散射、被吸收等物理现象，造成信号能量损耗。农田环境复杂多变，植被本身是影响信号传播的主要原因，无线信号传播特性的研究能为无线通信系统在农业中的应用提供必不可少的支持。无线信号在农田中的传播特性已经受到了众多国内外研究者的广泛关注。为此，分析了无线信号在植被中传播特性的研究现状，将已有的研究成果进行分类比较，从研究方法、传播环境、传播尺度，传播方式和极化方式等多个角度进行分析讨论。同时，对无线信号在植被中的传播特性的研究进行了总结和展望。
