Wideband Analysis of Mutual Coupling Compensation Methods

[摘要] The performance of various mutual coupling estimation and compensation methods is quantified and compared for wideband operation. Their main limitations and the required procedures to estimate the coupling matrix are outlined. It is determined that only the full-wave method is accurate at all frequencies. The performance tradeoffs associated with the other methods are described. General guidelines based on the electricalsize and separation of the array elements are formulated for each method. The results can be valuable for both wideband and narrowband receiving antenna arrays.
