摘要:

短波通信在移动通信、遂行通信中多数使用鞭状天线利用地波进行通信。为评估短波地波传播特性,将短波地波传播模型与天线仿真技术相结合,采用矩量法计算陆地鞭状天线的辐射特性。计算结果表明,对应不同的通信距离,存在一个最佳频段。

关键词: 短波通信, 鞭天线, 地波链路, 矩量法

Abstract:

Short-wave communications generally adopt ground-wave with whip antenna in mobile communications and carry-out communication.To assess the short-wave ground wave propagation,wave propagation model and antenna simulation technology are combined to calculate whip antenna radiation property with method of moments.Results show that there is an optimum frequency band corresponding to different communication distances.

Key words: Short-wave communications;whip antenna;ground-wave link;method of moments
