A new approach of pattern synthesis for array antennas of arbitrary geometry using the Conjugate Gradient method

In this paper we have presented a new approach for pattern synthesis for array antennas of arbitrary geometry. The far-field radiation pattern is matched to one that is prescibed by minimizing a global root-mean-square error. Using the Conjugate Gradient iterative scheme the storage and inversion of a large system matrix is omitted. As shown by numerical test cases presented in this paper, the present method offers an efficient and reliable numerical tool for (power) pattern synthesizing of arbitrary beam shapes.
