| 摘 要： | 机载天线间的隔离度是飞机系统电磁兼容性的主要参数之一,用来表征天线间的耦合强弱程度.在实际工程中,飞机上集中了大量天线,使得周围空间电磁环境很复杂.在研究机载天线电磁兼容性时,采用计算天线间的隔离度数值的方法来实现.本文先通过对配置在圆柱体模型上的两个天线的隔离度进行理论分析和计算,然后采用HFSS仿真软件对所需频带内的两个天线隔离度进行了仿真,并将其两者的结果进行了比较,从而实现对整个频带内的天线的电磁兼容性的正确预测和评估.

| Abstract: | Isolation between antennas is a primary parameter of electromagnetic compatibility(EMC) on airborne platform,which is the characterization of the degree of electromagnetic coupling.Electromagnetic environment for airborne platform is very complicate because of lots of antennas.The isolation between antennas is calculated in study of airborne electromagnetic compatibility.Based on the theoretical analysis and calculation of the cylinder model,the isolation between two antennas are simulated by HFSS in this p... |
