| 摘 要： | 通过电抗加载来控制方向图主瓣指向的天线称为电控无源阵列天线,简称ESPAR天线.提出了一种三单元H形缝隙耦合馈电贴片ESPAR相控阵天线,该天线通过分别改变加在两侧寄生辐射贴片馈电端的直流控制电压来改变相应的电抗加载值,从而使其实现宽波束扫描.给出了该天线的详细分析,以及电磁仿真结果,结果表明,该天线在H面上能实现-30°～30°的宽波束扫描.

| Abstract: | The antenna whose main beam of pattern can be controlled by loading appropriate reactance is named Electronically Steerable Passive Array Radiator,and ESPAR for short. In this paper,a three-element H-shaped aperture coupling patch ESPAR phased array antenna is proposed. The antenna makes wide-angle steering possible by making adjustments to the DC-controlled voltage applied to the patches of the feeding end on both sides,in an attempt to change the reactance loading value. The analysis of the antenna and EM... |
