Abstract

The invention relates to the technical field of communication antennas, and discloses a dual-frequency radiation unit and a base station antenna, wherein the dual-frequency radiation unit includes a carrier; the carrier includes a first body, a second body, and a third body; the second body and the third body are respectively It is vertically connected with the lower surface of the first body, and the second body and the third body are intersected; the upper surface of the first body is provided with a radiation surface, and the lower surface of the first body is provided with a parasitic component; one side of the second body is provided with There is a first feeding plane, one side of the third body is provided with a second feeding plane; the other side of the second body and the other side of the third body are respectively provided with a grounding plane, and the grounding plane is connected to the radiation plane. A dual-frequency radiation unit and a base station antenna provided by the present invention realize dual-frequency characteristics on a layer of dielectric board, avoid the disadvantages of multi-layer dielectric boards, and make the radiation unit meet the conditions of low profile, simple structure and easy assembly Under this condition, dual-frequency characteristics are realized, and the cost is low, and the production cycle is short.

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 ...
