Mutual coupling between port 1 of the array and the other three ports, when the array is in planar and bent state.

(a) Planar: mutual coupling between port 1 and 2

(b) Bent: mutual coupling between port 1 and 2

(c) Planar: mutual coupling between port 1 and 3

(d) Bent: mutual coupling between port 1 and 3

(e) Planar: mutual coupling between port 1 and 4

(f) Bent: mutual coupling between port 1 and 4
