| 摘 要： | 用脉冲电源产生亚纳秒高斯电脉冲给线元天线馈电,测试线元天线轴线能量的传输特性。实验结果表明,在相同轴线距离处,线元阵列天线轴线能量与单元天线轴线能量之比正比于天线阵列阵元数的平方;阵列天线轴线能量具有慢衰减传输特性;对线元阵列天线不同行、列作适当馈电延迟,可实现辐射电磁波束的空间扫描。所有实验结果在误差范围内与理论计算结果符合。

| Abstract: | Fed by sub-nanosecond pulse power,Radial energy of linear element antenna array is offered,the result indicate: The maximum energy of bounded beam is proportional to the square of the number of element of antenna array.The Radial energy curve of linear element antenna array is formed by non-decaying,slow-decaying and fast-decaying distance.Keeping the same line elements of antenna array feeding at same time while each row successive postpone properly,the beam can be restrained within the expected area.within the experimental error.All experimental results are accord with the analytical and numerical results. |

| Keywords: | linear element antenna array sub-nanosecond pulse slow-decaying property beam scanning |
