Abstract

An antenna apparatus for a portable terminal includes a main board and a display device. The main board has a ground for grounding and a feed terminal for feeding. The display device electrically communicates with the main board by the medium of a Flexible Printed Circuit Board (FPCB) and has an ElectroStatic Charge (ESD) prevention ground. If the display device is mounted above the main board, the ESD prevention ground of the display device comes in electric contact with the feed terminal of the main board, for emission.

Claims

1. An antenna apparatus for a portable terminal, the apparatus comprising:

a main board including a ground configured to provide an electrical ground and a feed terminal configured to provide an electrical connection; and

a display device configured to electrically communicate with the main board by the medium of a Flexible Printed Circuit Board (FPCB), the display device comprising an ElectroStatic Discharge (ESD) prevention ground, wherein the ESD prevention ground is disposed along an edge of the display device,

wherein, if the display device is mounted above the main board, the ESD prevention ground of the display device is configured to electrically contact the feed terminal of the main board, for emission,

wherein the display device comprises a display unit and a touch panel attached to the display unit, and

wherein the ESD prevention ground is realized in one of the display unit and the touch panel.

2. The antenna apparatus of claim 1, wherein the FPCB is configured to electrically connect the ESD prevention ground of the display device and the ground of the main board.

3. The antenna apparatus of claim 1, wherein the ESD prevention ground of the display device and the feed terminal of the main board are configured to electrically contact with each other by the medium of one of:

a Pogo pin and an elastic plate.

4. The antenna apparatus of claim 1, wherein the main board further comprises a matching circuit configured to connect to the feed terminal.

5. The antenna apparatus of claim 1, wherein the touch panel comprises:

a protection layer comprising PolyCarbonate (PC); and

an Indium Tin Oxide (ITO) layer attached to a bottom of the glass, the ITO layer configured to sense a touch.

6. The antenna apparatus of claim 1, wherein the ESD prevention ground has a resonance frequency of any one of Digital Multimedia Broadcasting (DMB), Global Positioning System (GPS), Bluetooth, and Wireless Fidelity (WiFi).

7. A portable terminal comprising:

a housing;

a main board disposed within the housing, the main board comprising a ground configured to provide an electrical ground and a feed terminal configured to provide an electrical connection; and

a display device configured to electrically communicate with the main board by the medium of a Flexible Printed Circuit Board (FPCB), the display device comprising an ElectroStatic Discharge (ESD) prevention ground, wherein the ESD prevention ground is disposed along an edge of the display device,

wherein, if the display device is mounted above the main board, the ESD prevention ground of the display device is configured to electrically contact the feed terminal of the main board, for emission,

wherein the display device comprises a display unit and a touch panel attached to the display unit, and

wherein the ESD prevention ground is realized in one of the display unit and the touch panel.

8. The portable terminal of claim 7, wherein the FPCB is configured to electrically connect the ESD prevention ground of the display device and the ground of the main board.

9. The portable terminal of claim 7, wherein the ESD prevention ground of the display device and the feed terminal of the main board are configured to electrically contact with each other by the medium of one of:
