ABSTRACT
An array antenna consists of a large family of elementary antennas located on a smooth surface in R3. The design problem consists of finding the best location of these sources on that surface in order to recover the same behavior as found in classical antennas. The objective functions are of two kinds: the feasible antenna should cover a precise area and the outside of this area should be minimized. The global synthesis of planar antenna arrays consists of optimizing, at the same time, positions and weights of the array elements in order to generate a desired radiation pattern. It is a highly nonlinear optimization problem.
