摘　　要：提出了一种新型的双频宽带单层反射阵天线。首先介绍了设计思路与方法,强调了非周期结构和不同频带单元间相互影响的问题,并给出了解决方案;然后提出了两种新型宽带单元作为双频带反射阵单元,并对单元之间的相位相互影响作了测试;最后进行了天线阵列的设计制作与测试。测试结果表明:天线高、低频之间的干扰较小,高、低频中心频率口径效率分别达到45%和49%。This paper presents a novel wideband single-layer dual-band reflectarray. First the design guidelines and method are discused, focusing on the non-peridie structure and mutual influences be- tween different band elements. Then two new wideband elements are proposed for dual-band re- flectarray, with mutual influences between the elements tested. The array test results indicate that the interference between high-frequency and low-frequency bands is small, with the high and low center frequency aperture efficiency of dual-band reflectarray up to 45% and 49% respectively.
