Problems solved by technology

[0006] At present, there is no antenna design scheme that can take into account the bandwidth and performance of the antenna while ensuring the width of the gap is reduced
[0007] On the other hand, due to the limitation of design size, the antenna in the prior art has a small radiation volume, which makes the performance of the antenna weak

Abstract

An antenna device and a mobile terminal. The antenna device comprises: a radiation unit and a grounding unit, wherein the radiation unit comprises a first radiation unit and a second radiation unit which are connected to each other; the grounding unit is a frame structure provided with an opening; the second radiation unit is located in the frame structure; the first radiation unit is located in the opening; two end surfaces of the first radiation unit are located in an extension direction of the opening; the two end surfaces of the first radiation unit and two end surfaces of the opening are separated from one another, so as to respectively form a first gap and a second gap; and the first radiation unit is connected to a feed point.

Description

technical field [0001] The present invention relates to communication technology, and more specifically relates to an antenna device and a mobile terminal. Background technique [0002] Mobile terminals, such as mobile phones or tablet computers, are indispensable communication and entertainment tools in modern life, and have an important impact on people's daily work and life. The antenna, as a device for transmitting and receiving signals of a mobile device terminal, directly affects the quality of communication, and thus affects people's work efficiency. [0003] At present, major mobile terminal manufacturers have launched mobile terminals with metal casings one after another. Mobile terminals with metal casings (that is, casings with metal texture) are widely loved and praised by users because of their stylish and beautiful appearance and the unique texture of metal itself. Mobile terminals with metal casings have become the mainstream development direction in the indu...
