Abstract

The invention relates to the technical field of terminal, and concretely relate to an antenna apparatus and a terminal. The antenna apparatus comprises a metal frame. A clearance area is between one end of the metal frame and the circuit board of the terminal. A radio frequency module arranged on the circuit board is connected to a feeding point which is connected to a feed metal wire. One end of the feed metal wire is connected to the metal frame. One side of the clearance area is also provided with an impedance loading device, and two ends of the impedance loading device are connected to the circuit board and the metal frame. According to the antenna apparatus and the terminal, a part of the metal frame is flexibly used as an antenna, by using the impedance loading device, the metal frame can be used as the antenna without opening a gap and cutting, the impedance loading device can be used for adjusting loading impedance so as to facilitate the tuning of the antenna, thus a multiple-communication-frequency-range antenna is realized, the cost can be reduced, and the reliability and appearance consistency of a product are improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an antenna device and a terminal. Background technique [0002] With the increasing popularity of handheld terminals such as mobile phones and tablet computers, the requirements for product appearance and wireless performance are both important and mutually restrictive. At present, most popular products usually use metal back shell or metal frame to improve the firmness of the product. Compared with plastic materials, it can also improve the overall appearance and grip of the product. [0003] However, in order to still achieve antenna performance when using a metal frame and a metal back shell, it is usually necessary to slit the metal back shell or the metal frame so that part of the cut metal area can be used as a part of the antenna. However, this will inevitably lead to the deterioration of the appearance consistency, the deterioration of product reliability and t...
