Abstract

A folding portable radio communication device has a plurality of bodies, one or more hinges for connecting the plurality of bodies so as to be mutually swingable. A first body in the plurality of bodies houses therein a microphone and a circuit board and, further, mounts therein an antenna part without the projection of the antenna part from the first body.

Claims

1. A folding portable radio communication device comprising a plurality of bodies, one or more hinges for connecting the plurality of bodies so as to be mutually swingable, wherein

a first body in the plurality of bodies houses therein a microphone and a circuit board and, further, mounts therein an antenna part without the projection of the antenna part from the first body.

2. The folding portable radio communication device according to claim 1, wherein the antenna part is built in the first body.

3. The folding portable radio communication device according to claim 1, wherein the antenna part is mounted in the first body in its end remote from the end of the first body to which the hinge is connected.

4. The folding portable radio communication device according to claim 1, wherein the plurality of bodies are constituted respectively by an upper body, which is located at the upper part when the folding portable radio communication device has been opened, and a lower body which is located at the lower part when the folding portable radio communication device has been opened,

said first body being the lower body.

5. The folding portable radio communication device according to claim 1, wherein the antenna part is disposed so as to be spread in a direction perpendicular to a direction in which the circuit board mounted within the first body is spread.

6. The folding portable radio communication device according to claim 1, wherein the first body is longer than a second body in said plurality or bodies and, when the folding portable radio communication device has been folded, the first body is projected beyond the second body.

7. The folding portable radio communication device according to claim 1, wherein the antenna part is a plate antenna.

8. The folding portable radio communication device according to claim 1, wherein the antenna part is a linear antenna.

9. The folding portable radio communication device according to claim 8, wherein the antenna part is a meander line antenna.

10. The folding portable radio communication device according to claim 8, wherein the antenna part is a Hula-Hoop antenna.

11. The folding portable radio communication device according to claim 8, wherein the antenna part is a helical antenna.

12. The folding portable radio communication device according to claim 1, wherein

the first body comprises a front part, which faces another body in said plurality of bodies when the folding portable radio communication device has been folded, and a back part which is put on top of the front part to constitute the first body, and

the front part in formed of an insulator.

13. The folding portable radio communication device according to claim 1, wherein

the first body comprises a front part, which faces another body in said plurality of bodies when the folding portable radio communication device has been folded, and a back part which is put on top of the front part to constitute the first body, and

the front part is formed of a metal and is electrically insulated from the antenna part.
