Abstract

The invention provides electronic equipment and an antenna device. The electronic equipment comprises a metal frame 10, wherein the first end face of the metal frame 10 is provided with a first gap g1 and a second gap g2; and a first antenna unit 20 equipped with a first radiation branch 21 which is formed through a first segment of the first end face of the metal frame 10, and is used for the transmitting and receiving of a first signal at a first frequency band B1. The first gap g1 is located at an end part of the first segment. The electronic equipment also comprises a second antenna unit 30, and the second antenna unit 30 is equipped with a second radiation branch 31 which is formed through a second segment of the first end face of the metal frame 10 and used for the transmitting and receiving of a second signal at a second frequency band B2. The first gap g2 is located at an end part of the second segment. The first antenna unit 20 and the second antenna unit cover a plurality of frequency bands of LTE (long terminal evolution) communication.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and more particularly, to an electronic device and an antenna device. Background technique [0002] With the development of communication technology, the operating frequency band of electronic equipment is gradually increasing. Taking mobile communication terminals as an example, currently used 2G and 3G dual-mode mobile communication terminals require the working bandwidth of the antenna to be at low frequency 824-960MHz and high frequency 1710-2170MHz or 1710-2025MHz. In addition, the working frequency band of mobile communication terminals of TD-SCDMA and TD-LTE (4G) technology will also involve the frequency band in 2300MHz-2700MHz. Therefore, the development of communication technology needs to increase the operating frequency band of the antenna. [0003] In order to realize multi-band communication, usually a plurality of antennas are provided, a feeding point is provided...
