摘　　要：本文提出了1种改进基于紧耦合超宽带偶极子相控阵天线单元间耦合度的方法,通过在辐射单元的印制板上下表面设计耦合结构,并使用通孔将两层连接起来,可有效增加单元之间耦合的电容量和电感量,在此基础上设计仿真了1种基于该种紧耦合形式的超宽带偶极子天线,通过仿真可以看出,阵列中天线单元VSWR小于3的带宽为2.53GHz~9.32GHz,达到了将近4个倍频程,也证明了该种方法的有效性。This paper proposes a method to improve the coupling degree between the phased array antenna elements based on the tightly coupled ultra-wideband dipole.By designing the coupling structure on the upper and lower surfaces of the printed board of the radiating element,and the two layers are connected by using through holes,which can effectively increase the capacitance and inductance of the coupling between the elements.On this basis,an ultra-wideband dipole antenna based on this tightly coupled form is designed and simulated.It can be seen from the simulation that the bandwidth of antenna elements in the array with VSWR less than 3 is 2.53 GHz~9.32 GHz,reaching nearly four octaves,which also proves the effectiveness of this method.
