把旋转场天线用作发射天线在电视广播等方面已经获得了十分广泛的应用。然而关于旋转场天线辐射场的分析,过去的书刊上却只有粗略的介绍和某些结论性的描述。这些分析和描述远不能满足天线教学和实践的需要。 把旋转场天线用作接收天线来接收椭圆极化波,特别是圆极化波的问题,迄今尚未引起人们的广泛注意。 本文系统地分析了旋转场天线辐射场的特性和参数的计算方法,详细地讨论了用旋转场天线接收椭圆极化波的理论,导出了它的最佳工作状态。在此基础上,作者建议把旋转场天线用作接收椭圆极化波(特别是圆极化波)的一种实际的接收天线型式。
The use of a rotating field antenna as a transmitting antenna has gained a very wide range of applications in television broadcasting and the like. However, regarding the analysis of the radiation field of the rotating field antenna, there are only some rough descriptions and some conclusive descriptions on past publications. These analyzes and descriptions are far from meeting the needs of antenna teaching and practice. The problem of using a rotating field antenna as a receiving antenna to receive an elliptically polarized wave, especially a circularly polarized wave, has not attracted much attention so far. This paper systematically analyzes the characteristics of the radiation field of the rotating field antenna and the calculation method of the parameters. The theory of receiving the elliptically polarized wave with the rotating field antenna is discussed in detail and the best working condition is derived. On this basis, the authors propose to use the rotating field antenna as a type of actual receiving antenna for receiving elliptically polarized waves (especially circularly polarized waves).
