Abstract :
This paper presents the application of optimization methods for the synthesis of antenna arrays. The desired pattern shall exhibit a shape that allows uniform distribution of the radiated power on the Earth. Besides beamshaping, the optimization methods allow controlling the level of the sidelobes. The synthesis technique is used to calculate the excitation coefficients for arrays composed of cavity-backed circularly polarized annular slot antennas.
