短波车载三环天线性能仿真分析

Simulation analysis on the performances of vehicle mounted three-loop HF antenna

在介绍短波车载三环天线组成和结构的基础上,对短波车载三环天线和短波车载4 m鞭状天线的输入阻抗、调谐匹配、方向图、最大辐射仰角和最大增益等参数指标进行了对比仿真分析后,对三环天线的性能和通信能力进行了论述.

The components and forms of HF vehicle mounted three - loop antenna are introduced at first. The HF vehicle mounted three - loop antenna and 4 m whip antenna are used to simulate and analyze the parame- ters such as inputting impedance, maximum elevation angle, pattern and maximum gain with different frequencies. The results between two types of antennas are compared. At last, the performances and communication abilities of three - loop antenna are discussed.
