Abstract

The invention provides a microstrip radiation unit for a 5G system and an antenna. The microstrip radiation unit comprises a PCB plate (1), a metal guiding sheet (2), a radiation body and a groundinglayer (6); the PCB plate (1) serves as a base material; the radiation body is a copper-clad layer and is attached onto the upper surface of the PCB plate (1); the metal guiding sheet (2) is suspendeddirectly above the radiation body; the grounding layer (6) is a copper-clad layer and is attached onto the lower surface of the PCB plate (1); the radiation body includes a radiation main body (3) anda microstrip line (5), the microstrip line (5) and the radiation main body (3) intersect at a feed point L1; the direction of the microstrip line (5) and the direction of the radiation main body (3)are identical; and the microstrip line (5) is provided with a matching section (4). According to the microstrip radiation unit of the invention, a microstrip line patch array form is adopted, and therefore, the microstrip radiation unit is simple in structure and can be quickly assembled, and provides a favorable technical basis for the miniaturization of a 5G base station antenna.

Description

technical field

[0001] The present invention relates to the technical field of antenna radiation units, in particular to a microstrip radiation unit and an antenna applied in a 5G system. Background technique

[0002] With the development of the mobile Internet and the Internet of Things, the network speed, network capacity, terminal connection number and air interface delay of the 4G mobile communication system can no longer meet the needs of the market and technological evolution. In the future, wider bandwidth, higher speed and higher power consumption are required. 4.5G and 5G technologies with lower latency, denser and more secure connections.

[0003] In response to the needs of the next-generation mobile communication system, 4.5G and 5G base station antennas will be different from the current conventional base station antenna forms and will appear in the form of arrays. The antenna radiating unit in the array form will directly cascade the T / R active components, and...

Embodiment Construction

[0029] The radiation unit designed by the present invention adopts the form of a microstrip patch element, has a simple structure and fast assembly, and provides a favorable technical basis for the miniaturization of the 5G base station antenna.

[0030] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0031] In the 5G era, the phase requirements of high-frequency array antennas require extremely high-precision control of coaxial cables, which is often difficult to achieve. The present invention can eliminate this influence and achieve precise phase control, thereby greatly improving the performance of mobile communication. . see figure 1 , figure 2 and image 3 , The radiation unit designed by the present invention adopts a plane structure and is integrally formed. It is mainly composed of a PCB board 1, a metal guide piece 2, a radiator, and a grounding layer 6. The PCB board...
