(DE) DUAL POLARISIERTE PLANARANTENNE, BASISSTATION UND HERSTELLUNGSVERFAHREN
(EN) DUAL POLARISED PLANAR ANTENNA, BASE STATION AND METHOD OF MANUFACTURE
(FR) ANTENNE PLANE À DOUBLE POLARISATION, STATION DE BASE ET PROCÉDÉ DE FABRICATION
Abstract
(EN) A dual polarised planar antenna (10) comprising first (12) and second (13) antenna elements having respective orthogonal polarisations, the antenna elements (12, 13) being arranged in a back-to-back configuration and fed directly by respective first and second antenna feeds (15), wherein the dual polarised planar antenna (10) further comprises a parasitic element (14) arranged between the antenna elements (12, 13) such that in-use the antenna feeds (15) are decoupled. Particularly suited to low profile antennas and compact antenna base stations. Also relates to a method of manufacture.
(FR) L'invention concerne une antenne plane à double polarisation (10) comprenant des premier (12) et second (13) éléments d'antenne ayant des polarisations orthogonales respectives, les éléments d'antenne (12, 13) étant agencés dans une configuration dos à dos et alimentés directement par des première et seconde alimentations d'antenne respectives (15), l'antenne plane à double polarisation (10) comprenant en outre un élément parasite (14) disposé entre les éléments d'antenne (12, 13) de telle sorte que, lors de l'utilisation, les alimentations d'antenne (15) sont découplées. Des antennes à profil bas et des stations de base d'antenne compactes sont particulièrement appropriées. L'invention concerne également un procédé de fabrication.
