大型长波天线支撑塔对电气性能影响分析
内容简介：大型长波天线通常需要多座高耸铁塔支撑，接地支撑塔及其纤绳对天线辐射性能有一定影响。传统分析方法为解析法，有一定局限性，无法计算局部结构变化对天线电气性能的影响。本文使用基于矩量法的FEKO软件对长波天线进行计算仿真，重点分析支撑塔及其纤绳接地/绝缘对天线电气性能的影响，通过计算分析得出，支撑塔及纤绳绝缘能有效地提高天线的有效高度，从而提高辐射效率，为长波天线工程实施起重要的指导作用。
Abstract：Large long-wave antennas usually have several supporting towers. The supporting tower and ropes can affect the antenna radiation property .Traditional calculation method of long-wave antenna is analytic method, which has certain limitations such as being unable to calculate the effect of local structure changing on the electrical properties of the antenna. The FEKO software based on MOM is used to calculate long-wave antennas in this paper. The effect of supporting towers and ropes insulation on the electrical properties of long-wave antennas is analyzed. According to the calculation, it can be found that the supporting tower insulation can improve the resonance frequency and the effective height of the antenna, which provide the guidance in the long-wave antenna engineering.
