Abstract

The invention provides an antenna device and a mobile terminal. The antenna device comprises an antenna body, an antenna feed source and a feed matching circuit, wherein the antenna feed source is connected with a feed point of the antenna body through the feed matching circuit; the antenna body is divided into a first antenna arm and a second antenna arm through the feed point; a first ground point is arranged on the first antenna arm and is grounded through a first tuning circuit; and a second ground point is arranged on the second antenna arm and is grounded through a second tuning circuit.The antenna device provided by the invention can be used as a variety of antennas, so that the number of the antennas which need to be arranged on the mobile terminal can be reduced, thereby reducingthe assembly space occupied by the antennas.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an antenna device and a mobile terminal. Background technique [0002] With the large-scale application of the 4th Generation mobile communication technology (4G for short) and the pre-commercial use of the 5th Generation mobile communication technology (5G for short), data and experience require mobile terminals with More and more antennas. In order to provide users with richer and more diverse services or experiences, current mobile terminals are usually provided with multiple antennas, for example, Global Positioning System (Global Positioning System, GPS for short) antennas, Long Term Evolution (LTE for short) antennas. , wireless fidelity (WIreless-Fidelity, WIFI for short) antenna, etc., because each antenna has a certain length, the overall size of multiple antennas is relatively large, resulting in a large assembly space occupied by the entire antenna syst...
