Beam steering is normally achieved by the use of phase shifters at each element of an array. The phase taper thereby produced causes a shift of the far-field pattern in sin θ space. An alternate approach to beam steering is presented in which a pair of interleaved arrays are employed. One array of the pair is fed entirely by currents of zero phase, while the other array is fed entirely by currents of quadrature phase. Beam steering is done by control of amplitude at each element. An example of this technique is presented and discussed.
