Abstract

The embodiment relates to a case apparatus including antenna elements, a shielding member interposed between the antenna elements and a protective part to encapsulate and couple the antenna elements and the shielding member. Even when the case apparatus is mounted on a mobile communication terminal, a near field communication between the mobile communication terminal and an external device is smoothly performed.

Claims

1. A case apparatus comprising:

antenna elements;

a shielding member interposed between the antenna elements; and

a protective part encapsulating the antenna elements and the shielding member the antenna elements are coupled to the shielding member while.

2. The case apparatus of claim 1, wherein the shielding member comprises a first shielding sheet and a second shielding sheet.

3. The case apparatus of claim 2, further comprising a correction member interposed between the first shielding sheet and the second shielding sheet.

4. The case apparatus of claim 2, further comprising a battery interposed between the first shielding sheet and the second shielding sheet.

5. The case apparatus of claim 1, wherein the protective part is detachably mounted on a mobile communication terminal.

6. The case apparatus of claim 5, wherein the antenna elements are configured to relay short range communication between the mobile communication terminal and an external device.

7. The case apparatus of claim 6, wherein the short range communication comprises NFC (Near Field Communication).

8. The case apparatus of claim 6, wherein the antenna elements comprise:
