The present invention provides a wireless communication system which employs Butler matrix combiners and circuit switching at transmitter and receiver antenna arrays to provide directive beamwidth capabilities. Such narrow beamwidths permit the communication system to determine and select the transmission path having an optimum signal quality. The antenna arrays are integrated in a multilayer construction which reduces power consumption, increases the coverage range, improves the efficiency of the antenna array, and which has lower fabrication costs.
La présente invention est constituée par un système de communication sans fil qui utilise des combinateurs à matrices de Butler et un commutateur de circuits installé dans les réseaux d'antennes émettrices et réceptrices pour obtenir un diagramme de rayonnement directif. Ces diagrammes de rayonnement à faisceaux étroits permettent aux systèmes de communication de déterminer et de choisir le trajet de transmission offrant la qualité de signal optimale. Les réseaux d'antennes sont intégrés dans une construction multicouche qui réduit la consommation d'énergie, accroît l'étendue de la couverture, améliore le rendement et a un prix de revient réduit.
