Abstract：Considering the issue of the analysis and calibration for complete mutual coupling of conformal 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.
