Unifying the Theory of Mutual Coupling Compensation in Antenna Arrays

The limitations of current mutual coupling compensation methods in antenna arrays are thoroughly reviewed. The theory of mutual coupling compensation is unified in such a way that efficient methods can be employed for calibrating both transmit and receive systems having arbitrary geometries. The theory leads to methods that can evaluate mutual coupling using either theoretical or experimental means. Reciprocity is studied through the careful comparison of receive and transmit analytical formulations. Examples involving various applications are presented for the validation of the theory. This theory has numerous applications and contributes to the areas of antenna theory, mutual coupling analysis, complex structure modeling, and antenna measurements.
