초록
In this study, we analyze the reduction of a cross-polarization(X-pol) isolation by using parasitic elements to eliminate the pattern-nulls of a 60 GHz 2×4 microstrip patch antenna array. In addition, we investigate the changes of the pattern-null suppression and X-pol isolation resulting from different alignments of the parasitic elements mounted above the array antenna. Through this study, we demonstrate the feasibility of using parasitic elements to suppress the pattern-nulls of a patch array antenna in a system requiring an adequate X-pol isolation.
