非理想馈电端口下的共形阵完备互耦分析与校正

The Complete Mutual Coupling Analysis and Calibration for Conformal Arrays with Nonideal Ports Fed

针对非理想馈电端口下共形阵列天线的互耦分析和校正问题,该文提出"结构模式互耦"和"天线模式互耦"的概念,其二者的叠加共同导致了共形阵列的完备互耦效应。论文基于全波数值分析和微波网络理论,提出了共形阵列完备互耦的分析和校正方法。最后,通过全波数值仿真分析了非理想匹配馈电下的12元柱面微带共形阵列天线,有效验证了完备互耦校正方法的有效性。

Considering the issue of the analysis and calibration for complete mutual coupling of conforlnal arrays with nonideal ports fed, the concepts of the ＂structure mode mutual coupling＂ and the ＂antenna mode mutual coupling＂ are proposed. These two kinds of mutual coupling induce the complete coupling effects. Based on the full wave numerical analysis and microwave net theory, the analysis and effective calibration techniques for conformal arrays＇ complete mutual coupling are proposed. Furthermore, the 12-element microstrip cylinder array with nonideal ports fed is simulated, which confirms the validity of the proposed method.
