本研究提出一种适用于E耦合微带相控阵天线的超材料互耦抑制结构。提出了一种用于去耦的配置缝隙组合互补开口环谐振器（SCCSRR）。详细分析了SCCSRR的抑制特性，并对其设计方法和参数进行了沿着分析。SCCSRR对已与微带相控阵天线集成在表面和接地平面上，而没有任何增加的制造复杂性。所提出的设计提供了额外的耦合抑制19分贝相比，非去耦阵列相同的尺寸。在3.7GHz天线阵中，耦合抑制达到-42dB。元件间隔保持在0.5（o），带有两个辐射元件的完整设计尺寸为84 x 44 mm（2）。
This study presents a tailored metamaterial structure for mutual coupling suppression in the E coupled microstrip phased arrays. Configured slot combined complementary split ring resonator (SCCSRR) is proposed for decoupling. A detailed analysis of the suppression characteristics of SCCSRR is presented along with its design methodology and parametric analysis. The SCCSRR pairs have been integrated with the microstrip phased array on surface and in the ground plane without any added fabrication complexity. The proposed design offers additional coupling suppression of 19 dB as compared with non-decoupled array of same dimension. The coupling suppression of -42 dB for 3.7 GHz array has been achieved successfully. The element separation is kept at 0.5 (o) and the complete design with two radiating elements measures 84 x 44 mm(2).
