三元组天线阵列控制方案研究

三元组天线阵列的精确控制是射频仿真暗室设计施工中关键环节,它直接影响到仿真试验的精度.本文从电磁场理论中能量流的概念出发,充分考虑三元组天线辐射单元相位对等效辐射中心的影响,提出了一种新的三元组天线阵列控制方案.该方案由于充分考虑了辐射单元相位因素,因此在建造大型辐射式仿真暗室天线阵列时,可以完全省去每个辐射单元后面的移相器,从而大大降低天线阵列的建设造价;由于该控制方案充分考虑了三元组天线单元间距对合成信号方位的影响,因此控制的精度也较原先有显著提高.

Research On Controlling the Triad Of Antenna Array

Precise control is the key technique in RFSS,it affects the test precision in anechoic chamber directly.This paper ana- lyses the affect of antenna phase to equal emission center using the concept of Poynting,and puts forward a new way to control the triad of antenna array.This way can leave out the equipment of the move phase,reduces the cost of antenna array,and enhances the precise of control because of considering the space between antenna.
