Title:
ANTENNA ARRAY AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2021/213407
Kind Code:
A1
Abstract:
Provided in the present application are an antenna array and a base station, the antenna array comprising: a plurality of high frequency radiation units, and a first attenuator and a first phase shifter connected in series, where the first attenuator and the first phase shifter connected in series form one-to-one correspondence connections with the plurality of high frequency radiation units; among the plurality of high frequency radiation units, a portion of the high frequency radiation units make up a sub-array for radiating a low frequency signal; the antenna array further comprises a low frequency feed unit and a high frequency feed unit; the low frequency feed unit is connected to the sub-array, and the high frequency radiation units within the sub-array may form a radiation wave corresponding to a low frequency antenna by means of the first phase shifter and the first attenuator causing wave combination of the high-frequency radiation units in the sub-array. The high frequency feed unit is used for feeding power to each high frequency radiation unit. It is apparent by the description that the antenna array used in embodiments of the present application only needs to be provided with one type of radiation unit, which simplifies the antenna array when compared to the use of multiple different types of radiation units in the prior art, and can also improve radiation performance of the antenna array.
