A WIRELESS COMMUNICATION NODE WITH ANTENNA ARRANGEMENT FOR DUAL BAND RECEPTION AND TRANSMISSION

摘要

This disclosure relates to a network node comprising an antenna arrangement with an antenna column. The antenna column comprises a first and second set of subarrays with at least two subarrays each. Each subarray comprises at least one antenna element. The first and second set of subarrays comprise antenna elements having a first polarization and antenna elements having a second polarization, orthogonal to the first polarization, respectively. Each set of subarrays is connected to a corresponding filter device via a corresponding phase altering device. Each filter device is arranged to separate signals at a first frequency band and signals at the second frequency band between respective combined ports and respective filter ports such that first filter ports are arranged for transmission and reception of signals at one frequency band, and second filter ports are arranged for reception of signals at the other frequency band.
