Mutual coupling in microstrip antenna array elements

The mutual coupling between adaptive antenna array elements degrades the performance of the array especially for direction finding purpose. There are many possible ways to compensate the coupling effects via electromagnetic analysis or via signal processing. We are going to follow the first approach to determine the mutual coupling and we are following signal processing to compensate the effects of the mutual coupling. Based on the results the compensation of the mutual coupling between array elements can also be corrected for minimizing the direction-of-arrival estimation.
