A kind of antenna module and electronic equipment

Abstract

The application discloses an antenna module and electronic equipment, which relate to the field of antennas. The antenna module is a four-patch antenna module, which can realize different working modes in higher frequency bands and lower frequency bands, and has the advantages of small size, small footprint, The characteristics of less space. The antenna module includes a dielectric layer and a floor. The side of the dielectric layer away from the floor is provided with four identical metal patches. Each metal patch is provided with an L-shaped slot. The four metal patches are wound around a preset point. Evenly distributed on the medium layer in a rotationally symmetrical manner, each metal patch is connected to the floor through multiple short-circuit holes, and the four metal patches are connected through cross lines. There are four microstrip lines on the side of the dielectric layer close to the floor, and each microstrip line corresponds to a metal patch. The first end of the microstrip line is connected to the excitation source, and the second end of the microstrip line is coupled to the metal patch. , the second end of the microstrip line is connected to the floor through a through hole, and the projection of the microstrip line on the metal patch intersects the L-shaped groove.

Description

technical field [0001] The examples of this application relate to the field of antenna technology, and in particular, to an antenna module and an electronic device. Background technique [0002] With the development of 5G technology, the increase in frequency bands and the demand for Multiple Input Multiple Output (MIMO) technology have led to a sharp increase in the number of 5G terminal antennas. The frame antenna technology is no longer sufficient to support the development of 5G terminal antennas. As an auxiliary means on the stage of history. [0003] At present, the industry's solution to 5G terminal antennas is "the main frame line antenna and the built-in surface antenna as a supplement", that is, more slots are opened on the frame to accommodate more wire antennas, and the surface antenna is used as an auxiliary to supplement coverage. Individual frequency bands that cannot be accommodated by the bezel wire antenna. The current 5G terminal research and development...

AI Technical Summary

Problems solved by technology

The current research and development idea of ​​"frame line antenna as the mainstay and built-in surface antenna as the supplement" for 5G terminals has led to many unsolvable technical problems

For example, the limited space of the frame line antenna leads to poor antenna performance and cannot meet the design requirements of 5G full-band 4×4 MIMO specification and 8×8 MIMO specification; the large number of frame line antennas leads to mutual interference between antennas, and the decoupling network design is complicated and deteriorated Antenna performance

[0004] In the existing mobile terminals, planar antennas have gradually become the mainstream of applications. However, due to the pursuit of thinner and lighter, large screens, large batteries, multiple cameras, multiple microphones, and multiple speakers, the existing mobile terminals occupy a large amount of space in the mobile terminal. Space, while the existing planar antennas are all single-mode coverage modes (one mode covers one frequency band), which has the disadvantage of large size and are difficult to apply to modern mobile terminal equipment
