    • The present invention relates to a self-grounded antenna arrangement (10) comprising a base or central portion (5) arranged in a first plane and a number of arm sections (1,2,3,4) associated with said central portion (5), which taper towards a respective end tip. It comprises an electric conducting material, each arm section being adapted to form a transition from the central portion and being bent backwards towards the central portion by more than 180° so that its end tip approaches a first side of the central portion, at an opening therein. The end tip is connected to feeding means for feeding via an arm section specific port, one specific port ( 11 1 , 11 2 ,11 3 ; 11 4 ;) for each arm section. Each arm section (1,2,3,4) comprises a mixed functionality of a curved monopole antenna and a loop antenna, and the antenna arrangement provides substantially uncoupled ports with far field functions that are almost orthogonal in polarization, direction or shape. The invention is in particular intended for use in MIMO antenna systems for statistical multipath environments.
    • 本发明涉及一种自接地天线布置(10),包括布置在第一平面中的基座或中心部分(5)和与所述中心部分(5)相关联的多个臂部分(1,2,3,4) ),其朝向相应的末端倾斜。 它包括导电材料,每个臂部分适于形成从中心部分的过渡部分,并向中心部分向后弯曲超过180°,使得其端部末端接近中心部分的第一侧,在开口处 在其中。 端头连接到馈送装置,用于经由臂部分特定端口馈送,用于每个臂部分的一个特定端口(111,112,113; 114;)。 每个臂部分(1,2,3,4)包括弯曲单极天线和环形天线的混合功能,并且天线装置提供基本上未耦合的端口,其具有在极化,方向或形状上几乎正交的远场功能。 本发明特别旨在用于用于统计多路径环境的MIMO天线系统。
