Feeding structure for antenna array, antenna array, and network node

Abstract

The present disclosure relates to a feeding structure for an antenna array, an antenna array, and a network node. The antenna array may include a plurality of subarrays each with at least one antenna element. The feeding structure may include at least one transmitting branch and at least one receiving branch for a subarray of the plurality of subarrays. The at least one transmitting branch and the at least one receiving branch may be arranged separately. Thus, feeding structure with specific transmitting branches for improving phase tuning density may be provided by embodiments. The feeding structure for the antenna array may include asymmetrically separated transmitting signal path and receiving signal path. The polarization type of the transmitting can be individually controlled while a pair of orthogonal polarization are realized for receiving. The phase control density can be separately controlled for transmitting and receiving as demand.
