A New Wideband Mutual Coupling Compensation Method for Adaptive Arrays Based on Element Pattern Reconstruction

Abstract EN

A new mutual coupling compensation method for wideband adaptive arrays is proposed.

The new method is developed by combining the element pattern reconstruction method and the system identification method.

The element pattern reconstruction method is valid and effective in the mutual coupling compensation for adaptive arrays such as dipole arrays and microstrip arrays.

Each entry of the wideband compensation matrix is represented as an analytical expression against frequency.

The polynomial coefficients and orders of all entries are obtained via the system identification method.

The new wideband compensation method is characterized by the good adaptability of element structures and polarizations owing to the advantages of element pattern reconstruction method.

A wideband microstrip array is designed to test the validity and effectiveness of the wideband compensation method.
