Summary:A quadri-polarization diversity antenna system is disclosed. According to embodiments of the present invention, the antenna system comprises an antenna array including a first row of dual-polarized antenna units and a second row of dual-polarized antenna units. Each of the dual-polarized antenna units includes a first antenna element and a second antenna element, which perpendicularly cross each other. In each row, the first antenna elements are conductively connected to form a first sub-array, and the second antenna elements are conductively connected to form a second sub-array. The antenna system further comprises an RF matrix, which selectively adjust phases of RF input signals so as to generate RF output signals to be provided to the sub-arrays. When the RF output signals are radiated by the dual-polarized antenna units, a first beam having +/-45° polarizations and a second beam having 0°/90° polarizations are formed, and the first beam and the second beam are formed in directions that spatially differ from each other. Un système d'antenne à diversité de polarisation à quadri-polarisation est divulgué. Selon des modes de réalisation de la présente invention, le système d'antenne comprend un réseau d'antennes comprenant une première rangée d'unités d'antenne à double polarisation et une seconde rangée d'unités d'antenne à double polarisation. Chacune des unités d'antenne à double polarisation comprend un premier élément d'antenne et un second élément d'antenne, qui se croisent perpendiculairement l'une l'autre. Dans chaque rangée, les premiers éléments d'antenne sont connectés de manière conductrice pour former un premier sous-réseau, et les seconds éléments d'antenne sont connectés de manière conductrice pour former un second sous-réseau. Le système d'antenne comprend en outre une matrice RF, qui ajuste sélectivement des phases de signaux d'entrée RF de façon à générer des signaux de sortie RF à fournir aux sous-réseaux. Lorsque les signaux de sortie RF sont émis par les unités d'antenne à double polarisation, un premier faisceau ayant des polarisations de +/-45° et un second faisceau ayant des polarisations de 0°/90° sont formés, et le premier faisceau et le second faisceau sont formés dans des directions qui diffèrent spatialement l'une de l'autre. 사중 편파 다이버시티(quadri-polarization diversity) 안테나 시스템이 개시된다. 본 발명의 실시예들에 따르면, 안테나 시스템은 이중-편파(dual-polarized) 안테나 유닛들의 제1 열과 이중-편파 안테나 유닛들의 제2 열을 포함하는 안테나 어레이를 포함한다. 상기 이중-편파 안테나 유닛들 각각은 서로 수직교차하는 제1 안테나 소자와 제2 안테나 소자를 구비한다. 각 열에서, 상기 제1 안테나 소자들은 전도적으로 연결되어 제1 서브어레이를 형성하고, 상기 제2 안테나 소자들은 전도적으로 연결되어 제2 서브어레이를 형성한다. 안테나 시스템은 RF 입력 신호들의 위상을 선택적으로 조정하여, 상기 서브어레이들에 제공되는 RF 출력 신호들을 생성하는 RF 매트릭스를 더 포함한다. 상기 RF 출력 신호들이 상기 이중-편파 안테나 유닛들에 의해 방사될 때, +/-45° 편파(polrizations)를 가진 제1 빔 및 0°/90° 편파를 가진 제2 빔이 형성되며, 상기 제1 빔 및 상기 제2 빔은 서로 공간적으로 상이한 방향을 향해 형성된다.
