Embodiment Construction

[0034] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The exemplary described embodiments below do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with aspects of the present disclosure as recited in the appended claims.

[0035] In practical applications, when opening cracks on the frame of electronic equipment to set antennas of different working frequency bands, as the number of antennas increases, the number of cracks also increases, which affects the strength of the metal structure and is not in line with industrial standards. Design requirements for appearance.

[0036] In order to solve the above technical problem, an embodiment of the pre...

Abstract

The invention relates to electronic equipment. The electronic equipment comprises a metal shell and a plurality of antennas working at different frequency bands; the frame of the metal shell is provided with at least one breaking joint; each frame in the two side frames of each breaking joint is used as a radiation structural body shared by at least one antenna; and each antenna comprises a signal circuit and a matching circuit, and the matching circuit is connected in series between the signal circuit of the antenna and the radiation structure body and is used for matching a signal of the corresponding working frequency band of the antenna and filtering signals of the corresponding working frequency bands of other antennas coupled through the breaking joint. In the embodiment, at least two antennas can be arranged on the two sides of each breaking joint, the number of the breaking joints on the frame can be reduced, the use efficiency of each breaking joint can be improved, and the strength of the metal structure can be guaranteed. Moreover, the matching circuit of each antenna has the functions of signal matching and signal filtering, so that the antennas on the two sides of the same breaking joint can work reliably.

Description

technical field [0001] The present disclosure relates to the technical field of antennas, in particular to an electronic device. Background technique [0002] With the development of 5G communication technology, electronic devices need to integrate more antennas to realize 2 / 3 / 4 / 5G communication. Taking the metal frame of electronic equipment as an example, the frame antenna surpasses the built-in antenna made by printing molding (PDS), laser laser (LDS) and flexible circuit board (FPS) in terms of bandwidth and efficiency, which makes antenna engineers hope to make more Multiple antennas are integrated into the metal frame of the electronic device. [0003] Considering that each antenna needs to send and receive signals in different frequency bands, and needs different lengths, it is necessary to open a break on the frame. However, as the number of antennas increases, the number of broken seams also increases, which affects the strength of the metal structure and does not...
