Dans cet article, un nouveau réseau de formation de faisceaux (BFN) réalisé en Broadside Coupled Stripline (BCS) est proposé pour alimenter des antennes réseaux 1 × 4 et 2 × 2 dans la bande de 28 GHZ. Le nouveau BFN est composé uniquement de coupleurs et de déphaseurs. Elle ne nécessite aucun crossover par rapport à la Butler Matrix (BM) conventionnelle qui nécessite deux crossovers. Les caractéristiques de couplage étroit et de faibles pertes du BCS permettent la conception d'un BFN compact et à large bande. Le nouveau BFN produit des différences de phase de (±90°) et (±45°, ±135°) respectivement dans les directions x et y. Son intégration avec une antenne réseau linéaire 1×4 réduit la surface du réseau de 70 % avec une amélioration des performances de gain par rapport au réseau conventionnel. L'intégration avec un réseau 2×2 permet la réalisation d'un balayage de faisceau 2D complet. Le concept proposé a été vérifié expérimentalement en mesurant les prototypes fabriqués du BFN, des antennes réseau de patchs 1D et 2D. Les gains maximum mesurés de 11.5 dBi et 11.3 dBi sont réalisés en θ0 = 14° et (θ0,0) = directions (45°, 345°) respectivement pour les réseaux de patchs 1D et 2D. La surface physique du BFN fabriqué est seulement (0.37λ0×0.3λ0×0.08λ0), tandis que les zones d'antennes réseau 1D et 2D sans lignes de transmission d'alimentation sont respectivement (0.5λ0×2.15λ0×0.08λ0) et (0.9λ0×0.8λ0×0.08λ0).

Abstract: In this article, a new Beamforming Network (BFN) realized in Broadside Coupled Stripline (BCS) is proposed to feed 1×4 and 2×2 arrays antenna at 28 GHZ-Band. The new BFN is composed only of couplers and phase shifters. It doesn't require any crossover compared to the conventional Butler Matrix (BM) which requires two crossovers. The tight coupling and low loss characteristics of the BCS allow a design of a compact and wideband BFN. The new BFN produces the phase differences of (±90°) and (±45°, ±135°) respectively in x- and y-directions. Its integration with a 1×4 linear array antenna reduces the array area by 70% with an improvement of the gain performance compared with the conventional array. The integration with a 2×2 array allows the realization of a full 2-D beam scanning. The proposed concept has been verified experimentally by measuring the fabricated prototypes of the BFN, the 1-D and 2-D patch arrays antennas. The measured 11.5 dBi and 11.3 dBi maximum gains are realized in θ0 = 14° and (θ0, φ0) = (45°,345°) directions respectively for the 1-D and 2-D patch arrays. The physical area of the fabricated BFN is only (0.37λ0×0.3λ0×0.08λ0), while the 1-D array and 2-D array antennas areas without feeding transmission lines are respectively (0.5λ0×2.15λ0×0.08λ0) and (0.9λ0×0.8λ0×0.08λ0).
