Description

  The present invention relates to a communication device such as a mobile phone, and more particularly to a communication device, a control method, and a control program that can use a shaft used as a rotating shaft of a hinge as an antenna.

  In recent years, communication devices such as mobile phones have become more and more multifunctional, thinner and smaller. For this reason, development has been performed to allow the entire printed wiring board built in the communication device to function as a dipole antenna. Hereinafter, a communication apparatus related to the present invention will be described with reference to FIGS.

  In the communication apparatus shown in FIG. 11, the upper substrate 1 and the lower substrate 2 that are separated from each other in a direct current manner function as a dipole antenna. 11 includes an upper substrate 1, a lower substrate 2, an upper housing 3, a lower housing 4, an upper and lower substrate connecting portion 5, a feed line 21, a matching circuit 9, and a wireless circuit 10. And a control circuit 11.

  The matching circuit 9 is for reducing reflection loss from the antenna. The matching circuit 9 supplies power to the power supply line 21. In the communication apparatus shown in FIG. 11, the upper substrate 1 and the lower substrate 2 function as radiating elements.

  However, when a dipole antenna is applied to a communication device that can be made thinner and smaller, as in the communication device shown in FIG. 11 described above, the following problems occur.

  The first problem is that the antenna characteristics when the communication device is folded are deteriorated due to the operation principle of the dipole antenna. FIG. 12 shows the direction of current when unfolding, and FIG. 13 shows the direction of current when folded. When the communication device is deployed, the current flowing through the upper substrate 1 and the lower substrate 2 is in the same direction as shown in FIG. However, when the communication device is folded, as shown in FIG. 13, the current flowing through the upper substrate 1 and the lower substrate 2 is in the opposite direction, so that the antenna characteristics are deteriorated.

  For this reason, the dipole antenna does not function as an antenna when folded. Therefore, it is necessary to provide a folding antenna separately, which causes structural limitations due to securing the antenna area.

  The second problem is that a metal cannot be disposed in the hinge portion in order to ensure good antenna characteristics. As shown in FIG. 14, when the reinforcing metal 22 is arranged in the hinge portion, the current flowing through the upper substrate 1 and the lower substrate 2 is reversed when deployed, so that good antenna characteristics cannot be ensured. For this reason, the reinforcing metal 22 cannot be disposed in the hinge portion, which causes a problem in securing the rigidity of the casing when it is reduced in thickness and size.

  The third problem is that the feed line of the dipole antenna is arranged near the hinge portion, and is therefore easily affected by manpower. As shown in FIG. 15, when the feeder line 21 is biased toward the end of the communication device, the antenna characteristics deteriorate when the hand approaches the vicinity of the feeder point.

  For this reason, in communication devices equipped with a shaft, the development of a communication device that can function as a feed line for a dipole antenna when the shaft is deployed and functions as an antenna for the communication device when folded. It will be seen as necessary.

  In addition, as a technical document filed earlier than the present invention, the feeding element and the hinge part as the upper element, the ground of the circuit board as the lower element, the dipole antenna as a whole operates, and the housing is opened, There is a document that discloses a portable radio device that has a high antenna gain (see, for example, Patent Document 1).

Further, there is a document that discloses a portable wireless device in which a tag antenna is arranged inside a hinge portion and data communication is performed with the hinge portion standing (see, for example, Patent Document 2).

  However, in Patent Documents 1 and 2, it is necessary to describe anything about the point that the shaft mounted on the communication device functions as a feed line for the dipole antenna when deployed, and functions as the antenna for the communication device when folded. There is no suggestion about sex. For this reason, in the technique of the said patent document 1, 2, the problem mentioned above will generate | occur | produce.
