antenna feed meaning in Chinese

天线馈电线

High power helical array antenna fed from single - layered radial waveguide
高功率单层径向线螺旋阵列天线的设计与模拟
Antenna feed impedance
天线输入阻抗
The antenna feed manner can be perfectly modeled accordingly , and less additional requirement for computer is needed . using this simulation method , the time - domain waveform has complete fidelity
此种激励设置方式只增加很少的计算机开销，就可以完全模拟各种类型天线的馈电方式，并有完全的时域波形保真性。
The serpentine feed is the core of a frequency scanning antenna feed system , which produce proper amplitude and phase distribution for the antenna arrays . most of all , it make the beam scanning over a large angle range by means of changing operating frequency
它为天线阵提供要求的幅度、相位分布，更为重要的是当频率发生少许变化时使线源的等相位面产生显著的倾斜，完成波束在空间扫描。
