Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a dual-frequency radiation unit and a base station antenna. Background technique [0002] With the advent of the Internet of Things era, there is a huge communication demand in the fields of smart home, smart city, and driverless driving. The traditional 4G network can no longer meet the market's demand for communication speed and capacity. The communication speed is faster and the capacity is higher. Big 5G technology came into being. [0003] In the field of base station antennas, the large-scale antenna array system (Massive MIMO) is considered to be the most potential transmission technology for 5G in the future. The 5G base station integrates the traditional remote radio unit (RRU) with the antenna system, squeezing the antenna The design space of the system requires a low profile for the 5G radiating unit; at the same time, since there are often hundreds of ...
