摘要

对雷达用l波段维瓦尔第天线中FR4衬底的损耗进行了分析。通过计算天线在不同频率下的增益，研究了导体损耗和介质损耗的影响。利用数学方程计算损耗，并借助电磁仿真模型进行描述。观察到介质损耗和导体损耗与衬底厚度成反比。分析表明，介质损耗与天线的几何形状无关。

Loss analysis of Vivaldi antenna for radar applications

The loss analysis of FR4 substrate in an L-band Vivaldi antenna for radar applications has been performed. The effect of both conductor loss and dielectric loss is studied by computing the gain of the antenna at different frequencies. The losses are computed using mathematical equations and described with the help of EM simulation models. It is observed that both dielectric loss and conductor loss are inversely proportional to substrate thickness. The analysis shows that dielectric loss is independent of antenna geometry.
