Antenna Device and Terminal
An antenna device and a terminal are provided. The antenna device includes: a shielding device, which at least comprises a first part made of a material capable of shielding a wireless signal, the shielding device being moveable, wherein the first part shields an antenna when located at a first position, making the antenna unable to receive and/or transmit a signal; the antenna works normally when the first part is moved out of the first position.
1 . An antenna device, comprising:
a shielding device, which at least comprises a first part made of a material capable of shielding a wireless signal, and the shielding device being moveable, wherein the first part shields an antenna when located at a first position, making the antenna unable to receive and/or transmit a signal; the antenna works normally when the first part is moved out of the first position.
2 . The antenna device according to claim 1 , wherein the shielding device further comprises: a second part made of a material capable of enhancing a wireless signal, which enhances the reception and/transmission of signal of the antenna when located at the first position.
3 . The antenna device according to claim 2 , wherein the first part is connected with the second part; the shielding device further comprises: a moving device, which is used to move the connected first part and second part, the first part is moved out of the first position while the second part is moved on the first position.
4 . The antenna device according to claim 3 , wherein the moving device comprises:
a sliding support, on which the first part and the second part are disposed;
a moving component, which is connected with the sliding support and is used to receive an external force to move the sliding support.
5 . The antenna device according to claim 1 , wherein the first position is located above the antenna.
6 . The antenna device according to claim 1 , wherein the first part is a metallic film, and/or the second part is a magnetic film.
7 . A terminal, comprising an antenna and an antenna device wherein the antenna device comprise:
a shielding device, which at least comprises a first part made of a material capable of shielding a wireless signal, and the shielding device being moveable, wherein the first part shields an antenna when located at a first position, making the antenna unable to receive and/or transmit a signal; the antenna works normally when the first part is moved out of the first position.
8 . The terminal according to claim 7 , wherein
the terminal further comprises: a back cover;
the antenna device is located between the back cover and the antenna.
9 . The terminal according to claim 7 , wherein
a sliding groove is provided on the back cover;
a switch part of the moving component is located in the sliding groove, and the switch part can move along the sliding groove after receiving an external force, thereby moving the sliding support.
10 . The terminal according to claim 7 , wherein the antenna is an NFC antenna.
11 . The antenna device according to claim 4 , wherein the first position is located above the antenna.
12 . The antenna device according to claim, wherein the first part is a metallic film, and/or the second part is a magnetic film.
13 . The antenna device according to claim 3 , wherein the first part is a metallic film, and/or the second part is a magnetic film.
14 . The terminal device according to claim 7 , wherein the shielding device further comprises: a second part made of a material capable of enhancing a wireless signal, which enhances the reception and/transmission of signal of the antenna when located at the first position.
15 . The terminal device according to claim 14 , wherein the first part is connected with the second part; the shielding device further comprises: a moving device, which is used to move the connected first part and second part, the first part is moved out of the first position while the second part is moved on the first position.
16 . The terminal device according to claim 15 , wherein the moving device comprises:
a sliding support, on which the first part and the second part are disposed;
a moving component, which is connected with the sliding support and is used to receive an external force to move the sliding support.
17 . The terminal device according to claim 16 , wherein the first position is located above the antenna.
18 . The terminal device according to claim 16 , wherein the first part is a metallic film, and/or the second part is a magnetic film.
