Mutual coupling reduction techniques in microstrip patch phased arrays

This thesis deals with the investigation of the mechanisms of the formation of mutual coupling and its suppression between a pair of patches located above the common ground plane. The thesis includes an analysis of mutual coupling formation and a proposal of techniques dealing with its suppression. To analyse the mutual coupling, a pair of patch elements in both polarizations was designed and their mutual coupling was investigated. A suitable variation of the techniques was selected based on a study of the available suppression techniques of mutual coupling. The antenna designed by the selected technique was simulated and later produced. With interest, the suppression technique was used, extended to an 8x1 element array, and the function of a phased antenna array was tested
