摘要
为满足通信系统的要求,经常需要在高耸的通信铁塔上架设多个天线。铁塔的结构对天线的辐射性能有一定的影响。传统分析方法为解析法,而铁塔结构相对复杂,使用解析法有一定的局限性,且相对复杂。论文使用基于矩量法的FEKO软件对架设在铁塔结构上的典型定向、全向天线的辐射性能进行计算仿真,重点分析铁塔结构对天线辐射方向、主瓣宽度、带宽等性能指标的影响。通过计算分析得出,铁塔的结构对天线的性能有一定程度的影响,为分析铁塔上天线间的电磁兼容问题起到了一定的指导作用。
Multiple antennas are often set up on a tall communication tower to meet the requirement of the communication system. Tower’s structure has a certain influence on the performance of the antenna radiation pattern Traditional calculation method of the antenna is analytic method, which has certain limitations on the analysis of the complicated tower structure. The FEKO software based on MOM is used to calculate and simulate the antenna radiation pattern of the typical directional and omnidirectional antennas in this paper. The problem focuses on the tower structure＇s influence of the antenna radiation pattern, the main lobe width, bandwidth and other performances. According to the calculation, the structure of the tower has a certain influence on the performance of the antenna, which can be guidance for analysis of the electromagnetic compatibility problems of the antennas on the tower.
