Abstract

The invention discloses an antenna device and electronic equipment. The antenna device comprises a first antenna unit, a switch unit and a second antenna unit, wherein the first antenna unit is connected with a transceiver through a feeder line and is used for receiving signals from the transceiver; the switch unit has a closed state and a disconnected state, and is provided with a first end and a second end, wherein the first end is a free end and can be switched between grounding and ungrounding, and the second end is a fixed end; one end of the second antenna unit is grounded, and the other end of the second antenna unit is connected with the second end of the switch unit, wherein coupled feeding is carried out on the second antenna unit through stimulation of the first antenna unit; when the switch unit is at the disconnected state, the first antenna unit and the second antenna unit form a first combination, and the working band is a first band; when the switch unit is at the closed state, the first antenna unit and the second antenna form a second combination, the working band is a second band; and the first band is different from the second band.

Description

Technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to the technical field of antenna design. Background technique [0002] The large-scale popularization of smart terminal devices such as smartphones and tablets has led to the explosion of mobile Internet applications. The large-scale deployment of 4G / LTE and WLAN hotspots has also made mobile Internet applications no longer limited to ordinary web browsing and picture sharing. High-definition video, 3D video, and virtual reality are getting closer and closer to large-scale commercial use. These applications not only bring users a feast of audiovisual, but also stimulate the further increase of network capacity. [0003] With the development of wireless technologies such as LTE and WLAN, the number of mobile communication users has grown rapidly, and spectrum resources have become more and more tense. As a result, a mobile termi...
