In this work, a linear array that is formed by placing elements along a straight line is considered to shape the beam and control the level of the side lobes by adjusting the amplitudes of the current in the array. The total radiated field, |E| is produced by using the N^th Bernstein polynomial, B_N(f;x). So that the well-known linear arrays and rest unrealized ones that uses the current distribution excitations for the required radiation, can be obtained as special cases from an unified analytical procedure by changing f_k coefficients in the Bernstein polynomial. The connection between arrays and Bernstein polynomial is established by considering current excitation symmetrical for obtaining real-valued array function, and by choosing an appropriate transformation between x and Ψ to make the array function and polynomial identical. By this new method, both broadside ( maximum radiation at θ = π/2) and end-fire (maximum …
