Antenna device of mobile terminal
An antenna device of a mobile terminal that can secure radiation performance is provided. The antenna device having a battery cover composed of a metal material includes a radiation unit for transmitting and receiving a signal, a feeding unit formed at an end portion of a first side of the radiation unit for electrically connecting the radiation unit to a Printed Circuit Board (PCB), and a ground part disposed a predetermined distance from the feeding unit and formed at a second side of the radiation unit. When the battery cover is fastened to the mobile terminal, the ground part contacts a first side of the battery cover.
1. A mobile terminal comprising:
a first body composed of a metal material;
a second body composed of a nonmetal material; and
an antenna device disposed in second body,
wherein the antenna device comprises:
a radiation unit for transmitting and receiving a signal;
a feeding unit for electrically connecting the radiation unit to a Printed Circuit Board (PCB); and
a ground part disposed a predetermined distance from the feeding unit and extending from the radiation unit,
wherein the ground part is fastened to the first body.
2. The mobile terminal of claim 1 , further comprising a carrier for mounting the antenna device.
3. The mobile terminal of claim 1 , further comprising a connection member for electrically connecting the feeding unit and the PCB.
4. The mobile terminal of claim 3 , wherein the connection member comprises a C-clip.
5. The mobile terminal of claim 4 , wherein the C-clip is integrally formed with the feeding unit.
6. The mobile terminal of claim 1 , wherein the first body is made from Steel Use Stainless (SUS).
7. The mobile terminal of claim 1 , wherein the radiation unit is formed as a monopole antenna or a Planar Inverted-F Antenna (PIFA).
8. The mobile terminal of claim 1 , further comprising a third body composed of a metal material that contacts the first body at a side of the first body, and mounts the PCB.
9. The mobile terminal of claim 8 , wherein the third body contacts a ground of the PCB at a side of the PCB.
10. The mobile terminal of claim 1 , wherein the first body contacts a ground of the PCB.
11. The mobile terminal of claim 1 , wherein the ground part contacts a ground of the PCB.
12. The mobile terminal of claim 1 , wherein the ground part perpendicularly extends from a length-wise side of the radiation unit.
