Abstract : In this PhD thesis, some feed networks are studied. First, a N x N symetric Butler matrix is considered. Analitical formulas allowing constructing its [S] matrix are founded and demonstrated. Second, a multibeam antenna focal array based on 3-D directional couplers is considered. This device has a high level of re-use of its radiating elements. Therefore, its global size is reduced. Its conception is explained. Measurement are exposed. Last, a mecanic / electronic device is studied. It is used for tracking. It is a complex device with several parts. The fact that the conception of each part depends on each other is highlighted. Compromises and choices need to be made.
