渐进圆锥D-dot电场传感器频响分析
|
摘要
基于等效电路建立渐进圆锥D-dot电场传感器的传递函数模型,使用CST仿真分析了端接负载阻值、地平面半径和有效面积对传感器频域响应的影响。给出展宽传感器工作频带时端接负载阻值、地平面半径和有效面积的约束条件,为渐进圆锥D-dot电场传感器的优化设计提供参考。
The transfer function model of the asymptotic conical D-dot electric field sensor is established based on the equivalent circuit. The influence of the termination load resistance, ground plane radius and effective area on the frequency domain response characteristics of the sensor is analyzed by CST simulation. The constraints of termination load resistance, ground plane radius and effective area are given when the working frequency band of the sensor is broadened, which can provide reference for the optimization design of the tapered D-dot electric field sensor.
