Abstract

The device has a number of antenna elements arranged at row and column intersections and mirror symmetrically to form an orthogonal matrix. The central column(s) has a certain number of antenna elements and the outer columns have fewer and the number of elements per column is not greater than the number in the columns closer to the line of symmetry.
