The invention discloses an antenna device and a mobile terminal. The antenna device is applied to the mobile terminal, wherein the mobile terminal comprises a conductive frame; the conductive frame is provided with a slot, a first frame segment and a second frame segment; the first frame segment and the second frame segment are located at two sides of the slot; the antenna device comprises a feed point, a first matching circuit, the first frame segment, the second frame segment, a second matching circuit and a tuning component; the first matching circuit is connected between the feed point and the first frame segment in series; the tuning component and the second matching circuit are sequentially connected between the ground and the second frame segment in series; the slot is used for achieving electric coupling between the first frame segment and the second frame segment to achieve a feed loop from the feed point to the ground; and the tuning component is used for adjusting parameters of the feed loop to change the frequency of the antenna device. According to the antenna device, the bandwidth of an antenna can be effectively expanded.
Description
technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna device and a mobile terminal using the antenna device. Background technique [0002] The appearance design of metal material is more textured, so mobile phones using metal casings gradually occupy the mainstream of the market. The appearance of the metal casing broke the design idea of the traditional mobile phone antenna and greatly increased the difficulty of antenna design. In the prior art, it is considered to use the metal case as a part of the antenna, and use the metal case for signal radiation. With the evolution of mobile communication technology, more and more frequency bands are applied to mobile terminals, which requires mobile phone antennas to have good compatibility and work on multiple frequency bands at the same time. However, the current mobile terminal using the metal casing as a part of the antenna cannot effectively broaden the frequen...
