Embodiment 1

[0034] refer to Figure 1-4 , in this embodiment, the antenna applied on the metal casing of the mobile terminal includes a metal back cover and an antenna unit, the antenna unit includes a feeding probe, an insulating sleeve and a reflection cavity, and the reflection cavity is formed by the metal back cover being recessed inward The cavity, the reflective cavity includes the first wall and the second wall; one end of the feed probe is connected to the first wall, the middle is connected to the second wall through an insulating sleeve, and the other end is welded to the feed signal line. The signal line is set on the main board of the mobile phone.

[0035] In this embodiment, the feeding probe is used to connect the first wall of the metal back cover and the feeding signal line to complete the feeding process of the antenna and radiate signals to the outside. In this embodiment, the installation position of the reflective cavity on the mobile phone, the form of the feeding ...

Embodiment 2

[0037] refer to Figure 1-4 , this embodiment is similar to Embodiment 1. Further, 8 antenna units are arranged on the metal back cover, and every 4 antenna units are 1 group of antenna groups, and 2 groups of antenna groups are respectively arranged on the long sides of the metal back cover , the reflective cavity is a square groove opened on the back of the metal back cover by CNC (Computer numerical control, CNC machine tool), when the length of the reflective cavity is 1 / 2 working wavelength to 1 working wavelength of the antenna unit, and the height is the antenna unit Better directional radiation can be achieved when the width is 1 / 8 to 1 / 2 of the working wavelength of the antenna unit and 1 / 10 of the working wavelength to 1 / 2 of the working wavelength of the antenna unit. Grooving the metal back cover by CNC and other processes is relatively simple and convenient, and does not affect the overall appearance of the back cover. Figure 5 It is the reflection coefficient c...

Embodiment 3

[0039] refer to Figure 7, the 5G antenna of this embodiment is similar to Embodiments 1 and 2. Further, the A area is the position where the LTE diversity antenna, GPS, and WIFI antenna are placed, the B area is the placement position of the LTE main antenna, and the C area is the 5G antenna placement.

Abstract

The invention discloses an antenna applied to a metal shell of a mobile terminal. The antenna comprises the metal shell and at least one antenna unit; and each antenna unit comprises a feed probe, aninsulating bushing and a reflection cavity, wherein the reflection cavity is a cavity formed after the metal shell is concaved inwards and comprises a first wall and a second wall, one end of the feedprobe is connected with the first wall, the middle of the feed probe is connected with the second wall through the insulating bushing, and the other end of the feed probe is connected with a feed signal line. The invention further provides an antenna system applied to the metal shell of the mobile terminal. Accordingly, by means of feeding of the feed probes and the structures of the reflection cavities, the 5G antenna can be arranged on the side edge of the mobile terminal to be capable of coexisting with 3G, 4G, GPS and WIFI antennas.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna and an antenna system applied to a metal casing of a mobile terminal. Background technique [0002] 5G (5th-Generation, the fifth-generation mobile communication technology) is aimed at the human information society after 2020. Although the relevant technologies have not yet been fully finalized, it is foreseeable that 5G with high speed, low latency, massive device connections, and low power consumption will Communication technology occupies an important position in the future society. As the core component of 5G terminal equipment, 5G terminal antenna will play an active and important role in promoting and promoting the development of mobile terminals such as new generation mobile communication systems and 5G mobile phones. [0003] Unlike the omnidirectional radiation antenna of 4G mobile phones, 5G mobile phones require beam-forming antenna arrays for millimeter ...
