摘要:In this paper we will carry out the study and the development of an approach of interferences rejection, based on a deterministic optimization method known as Mininmax method. This approach allows an optimal research of the feed law as well as the space repartition of radiant elements to synthesis a noises- adaptive microstrip antenna array. Therefore, this method permit to find the vectors of feed law and the space distribution of the radiant elements so that the obtained diagram respect the limits imposed by a pattern shape in which intervals of noises rejection are specified. With this manner, the radiation diagram fulfils the user’s requirements and avoids the degradation caused by noises. In this way, here, we will use the Minimax method to resolve the problem of interfering signals rejection intervening in the directions of radiation of linear microstrip antenna array while respecting a desired pattern shape. The synthesis is carried out by action on the electrical (amplitudes and the phases of feed) and geometric (space distribution of the radiant elements) parameters. Our goal is thus not only to make rejection of the noises but also to control the sides lobes levels to attenuate them
