摘要
为了准确确定非平面相控阵列天线在波束形成时各单元天线的相位中心,提出了一种借助三维场仿真软件HFSS计算单元天线相位中心的方法,并计算了某变指向通信天线单元天线的相位中心,研究了单元天线相位中心对天线波束形成的影响。仿真结果表明,该方法是有效的。
The phase center of each element antenna is not necessarily to be determined accurately for beam forming of planar phased - array antenna, but it is necessary for that of non - planar phased - array antenna, or phase is not set correctly and antenna performance is decreasing. In this paper, a new method of computing the element antenna phase center is proposed, and the element antenna phase center of a certain alternating - direction communication antenna is computed, and the effect of element antenna phase center on beam forming of non - planar phased - array antenna is studied. The simulation results demonstrate the effectiveness of the new method.
