【摘要】：為了抑制陣列天線單元的表面波,并減小陣元間的耦合效應(yīng),研究了電磁異向介質(zhì)材料在抑制陣列天線互耦效應(yīng)中的應(yīng)用.基于開口諧振環(huán)(Split-Ring Resonator,SRR)負(fù)媒質(zhì)材料特性,將SRR結(jié)構(gòu)單元加載于陣列天線之中,提出了具有互耦抑制效應(yīng)的天線設(shè)計方法.仿真結(jié)果表明:加載SRR結(jié)構(gòu)單元后,天線諧振工作頻點處的耦合系數(shù)降低了8.8dB,即由原來的-16.3dB降低到了-25.1dB,而對天線陣列的增益和方向圖沒有太大的影響,可以滿足工程的基本要求.為設(shè)計低耦合的微帶陣列天線提供了理論支持.
[Abstract]:In order to suppress the surface wave of array antenna elements and reduce the coupling effect between array elements, the application of electromagnetic anisotropic dielectric material in suppressing the mutual coupling effect of array antenna is studied. Based on the material characteristics of Split-Ring Resonator (SRR) negative medium, the SRR structure element is loaded into the array antenna, and an antenna design method with mutual coupling suppression effect is proposed. The simulation results show that the coupling coefficient at the resonant frequency point decreases by 8.8 dB, from -16.3dB to -25.1dB, but has no great effect on the gain and pattern of antenna array. Can meet the basic requirements of the project. It provides theoretical support for the design of microstrip array antenna with low coupling.
