摘要
在简单分析“T”形天线和地波传输特点的基础上,以行业标准中对NDB覆盖半径和覆盖区中最小场强为切入点,运用电磁波传输和天线与地网的工程公式,探索了NDB天线和地网的设计原理和计算方法。据此建立相应的数学模型。
The ＂T＂ shape antenna and radio transmission feature is analyzed. According to the standard of the covering radius and the strength of the electric field the engineering formula of the ＂T＂ shape antenna and radio transmission is used. The design principle and calculation of the NDB antenna and ground grid is explored.
