Abstract

A mobile communication terminal includes two housings and a hinge portion for movably coupling the housings together. The terminal further includes: a non-contact communication portion for conducting close range wireless communication; an operation portion; and a display portion. The non-contact communication has a loop-like antenna disposed in one of the housings. The display portion displays information with regard to a communication status of the close range wireless communication. Another communication terminal includes a housing having a display portion and an operation portion disposed therein; and a non-contact communication portion for conducting close range wireless communication. The non-contact communication portion has a loop-like antenna formed in a region of the housing having the display portion disposed therein.

Claims

1. A mobile communication terminal having two housings and a hinge portion for movably coupling the housings together, comprising:

a non-contact communication portion for conducting close range wireless communication;

an operation portion; and

a display portion,

wherein the non-contact communication portion comprises a loop antenna disposed in one of the housings, and

the display portion displays information with regard to a communication status of the close range wireless communication wherein the loop antenna is patterned on a circuit board in the mobile communication terminal wherein the circuit board has a through hole formed at a center thereof.

2. A mobile communication terminal according to claim 1, wherein the information includes at least information whether communication with an external device is successful or not.

3. A mobile communication terminal according to claim 1, wherein the loop antenna has a loop of at least two turns.

4. A mobile communication terminal according to claim 1, wherein a magnetic substance sheet is disposed proximate to the loop antenna.

5. A mobile communication terminal according to claim 4, wherein the magnetic substance sheet is disposed in at least a region corresponding to a region inside a loop of the loop antenna.

6. A mobile communication terminal according to claim 4, wherein the magnetic substance sheet comprises a material having a magnetic permeability higher than one to increase a magnetic flux density inside a loop of the loop antenna.

7. A mobile communication terminal according to claim 1, wherein the hinge portion foldably couples the two housings together.

8. A mobile communication terminal according to claim 1, wherein the hinge portion comprises two rotation axes.

9. A mobile communication terminal according to claim 1, wherein the display portions are disposed on each of opposing sides of the two housings.

10. A mobile communication terminal having two housings and a hinge portion for movably coupling the housings together, comprising:

a non-contact communication portion for conducting close range wireless communication;

an operation portion; and

a display portion,

wherein the non-contact communication portion comprises a loop antenna disposed in one of the housings, and

the display portion displays information with regard to a communication status of the close range wireless communication, wherein one of the housings comprises the display portion, the other of the housings comprises the operation portion, and

the loop antenna is disposed proximate to an outer periphery of the housing comprising the operation portion, wherein the hinge portion comprises two rotation axes, and wherein the operation portion is disposed on at least two faces of the other of the housings and is operable when the two housings are folded together.
