| 摘 要： | 研究了数字移相器提供的量化相移对正六边形相控阵天线扫描方向图的影响。使用一定精度移相器可降低馈源阵列的量化误差,而天线的方向图和增益只有微小的变化。分别选择2位、4位和6位移相器,比较采用连续相移和不同精度的量化相移时,天线辐射方向图的变化。通过对比分析可选择合适的数字移相器。

| Abstract: | This paper deals with the effect of the quantitative phase controlled by the digital phase shifter to the patterns of the hexagonal phased array antenna.Quantitative error will be depressed by using the phase shifter,and the antenna patterns and gain will be changed a little.The 2 bit,4 bit and 6 bit phase shifter are chosen respectively in this paper.According to the comparison of the continual phase and the quantitative phase with different precisions,the change is presented.The right digital phase shifter is selected by analyzing in the contrast. |
