    • A dual-polarized antenna (10) with good isolation between feed ports (13a, 13b) and high similarity with respect to the radiation patterns is provided. An antenna (10) includes a patch (11), four symmetrically arranged feed structures (12a-12d, 15), two feed ports (13, 13b) and a feed network (14). Radiation pattern similarity is obtained by the pair-wise symmetrical, orthogonal layout of the feed structures (12a-12d, 15). Good isolation between feed ports (13a, 13b) is achieved through a feed network (14) divided into two network parts (14a, 14b) where each network part (14a, 14b) is designed so that each coupling between a network part (14a, 14b) and a feed structure (12a12d, 15) belonging to the other polarization is cancelled by a mirrored coupling with the other feed structure (12a-12d, 15) belonging to the polarization. In addition, a network part (14a, 14b) is laid out so that its corresponding feed structures (12a-12d, 15) are fed with supporting signals of equal magnitude.
    • 提供了在馈电端口(13a,13b)之间具有良好隔离并且相对于辐射图案具有高相似性的双极化天线(10)。 天线(10)包括贴片(11),四个对称布置的馈送结构(12a-12d,15),两个馈送端口(13,13b)和馈电网络(14)。 通过进给结构(12a-12d,15)的成对对称的正交布局获得辐射图案相似度。 馈送端口(13a,13b)之间的良好隔离通过被分成两个网络部分(14a,14b)的馈电网络(14)实现,其中每个网络部分(14a,14b)被设计成使得网络部分(14a,14b)之间的每个耦合 ,14b)和属于另一极化的馈电结构(12a12d,15)通过与属于偏振的另一个馈电结构(12a-12d,15)的镜像耦合来抵消。 此外,布置网络部分(14a,14b),使得其相应的馈送结构(12a-12d,15)被馈送相同大小的支撑信号。

    • A node in a wireless communication system comprising at least a first cell region and a second cell region, where cell borders delimit between different cell regions. The node comprises at least a first antenna function with a first antenna radiation lobe and a second antenna function with a second antenna radiation lobe, the radiation lobes being arranged to cover the first cell region at the same time. For each cell region, only one of the antenna radiation lobes is intended for communication at each cell border. Furthermore, the first antenna radiation lobe is arranged for signals at a first frequency band, and the second antenna radiation lobe is arranged for signals at least a second frequency band.
