We present a procedure for the optimization of array antennas that conform to circular cylinders in two space dimensions. For a phase‐mode excitation of the antenna, a large number of antenna element designs are compared in terms of two objectives: (1) the active reflection coefficient and (2) the far‐field distortion with respect to the excited phase‐mode. This analysis yields Pareto fronts with respect to the two objectives and appropriate designs are selected based on the information collected for the useful phase modes given a specific frequency band. This antenna element design is used for the pattern synthesis, where we optimize a linear combination of (1) requirements on the directive gain and (2) similar requirements on the power reflected from the array antenna aperture.
