N2 - To suppress the strong mutual coupling among 2N patch antenna arrays, a very simple decoupling method is presented in this article, where only a metal block is utilized and loaded in the center of the 2N arrays. With the proposed method, the coupling between horizontal, vertical as well as diagonal pairs of adjacent antenna elements is well suppressed to a low level. To verify the practical performance, a 28 antenna array centered at 3.5 GHz and integrated with the proposed decoupling method is further developed and fabricated. The measured results denote that the maximum mutual coupling among the array is suppressed from 15.4 dB to 26.9 dB, with a fairly low insertion loss level. The design and implementation of the proposed decoupling method are very simple with a low profile and can be widely used for large-scale array applications with the 2N configuration.
