摘要
天线之间的耦合影响是短波通信台站建设中必须考虑的一个重要因素,采用SuperNEC(Super Numerical Elec-tromagnetics Code)天线数值计算软件与微波网络理论相结合的方法分析了短波线天线之间的耦合影响。该方法先将多天线系统等效为微波网络,然后通过SuperNEC仿真软件得出天线分布电流并计算出等效网络的导纳矩阵Y,利用该导纳矩阵Y就可得到天线之间的耦合度。分析证明该方法理论正确,并且对多天线的安装布局有重要的指导作用。
Coupling between antennas is very important parameter for HF signal station. SuperNEC( Super Numerical Electromagnetics Code) and microwave network theory are used for the analysis of coupling between antennas in this paper. The multiple antennas system is equivalent to a microwave network , and the admittance matrix of the network can be obtained by SuperNEC. Using the admittance matrix, It analyzes the characteristic of coupling between two antennas. It proves by analysis that the method is theoretically correct and can be used as a guidance for the installation disposition of multiple antennas.
