| 摘 要： | 对数周期天线是一种宽带天线 ,单个天线单元的带宽可以很宽 ,但其宽带特性在组阵时将受到一定的影响 ,在相控阵中更受到扫描角的限制 ,文中采用非相似元的方法有效地解决了四倍频程相控阵天线扫描时宽带和宽角的矛盾 ,扩展了对数周期天线在相控阵中的应用

| Abstract: | Logarithmic antenna is one of the wide band antenna.The frequency band of single element can be very wide,but it's wide band speciality may be affected when it is used in array and limited by the scan angle in phased array. In this paper,we use the method of non similar element to get over the conflict of the wide band and wide angle when the fourfold-frequency phased array is scanning,which makes logarithmic antenna widely used in phased array |

| Keywords: | phased array non similar element logarithmic antenna |
