CA 2191956

An antenna for a base station in a mobile radio communication system with at least one base station and at least one mobile station is disclosed. The antenna comprises a microstrip antenna array with a matrix of microstrip patches with at least two columns and two rows. In addition, a plurality of amplifiers is provided wherein each power amplifier is connected to a different column of microstrip patches. Finally, beamformers are connected to each power amplifier for determining a direction and shape of narrow antenna lobes generated by the columns of microstrip patches.

L'invention se rapporte à un agencement d'antenne pour une station de base dans un système de radiocommunication mobile comprenant au moins une station de base et au moins une station mobile. Ledit agencement d'antenne comporte un groupement d'antennes microruban doté d'une matrice de connexions à microruban composée d'au moins deux colonnes et deux rangées. En outre, une pluralité d'amplificateurs est prévue, chaque amplificateur de puissance étant connecté à une colonne de connexions à microruban différente. Enfin, des éléments conformateurs de faisceau sont connectés à chaque amplificateur de puissance afin de déterminer la direction et la forme de lobes d'antennes étroits générés par les colonnes de connexions à microruban.
