Abstract
An antenna array includes an antenna assembly. The antenna assembly includes a plurality of elements. The antenna assembly is configured to measure a reference combined parameter of a reference element of the plurality of elements, measure a first combined parameter of the reference element and a first neighbor element of the plurality of elements and being adjacent or diagonal with respect to the reference element, calculate a differential parameter according to the first combined parameter and the reference combined parameter, and adjust a parameter of the first neighbor element according to the differential parameter. The parameter of first neighbor element is a phase or a amplitude of first neighbor element. The first combined parameter includes a coupling contribution of the first neighbor element and the reference element, and contributions from a path of the first element and a path of the reference element.
