Abstract
Official abstract text for this publication.
Embodiments of the present invention relate to the field of communications technologies, and provide a base station antenna and a base station antenna feed network. The base station antenna includes a transceiver array, a first-level vector synthesis network, a second-level phase shifter array, a second-level vector synthesis network, and an antenna unit array. By using the second-level vector synthesis network, the base station antenna makes phase differences between multiple vector signals sent to antenna units smoother, thereby extending an adjustable range of a downtilt on the premise that the number of transceivers is as small as possible.
First claim
Opening claim text (preview).
What is claimed is: 1. A base station antenna, comprising a transceiver (TRX) array, a first-level vector synthesis network, a second-level phase shifter array, a second-level vector synthesis network, and an antenna unit array, wherein: the TRX array comprises N TRXs, which are configured to output N vector signals, wherein N is a natural number greater than or equal to 2; the first-level vector synthesis network is configured to implement vector synthesis for the N vector sign…
