Abstract

PROBLEM TO BE SOLVED: To make a terminal case small and to allow the user to make a speech while a patch antenna is detached from a head by providing a step difference to which the patch antenna is fitted when a support means is contained to the terminal case. SOLUTION: A patch antenna 2 is placed on an upper face of a terminal case 1 and the antenna 2 is integrated with the terminal case 1 in the standby state, and a support 3 to which the patch antenna 2 is fitted automatically or manually is extracted from the contained part in the case 1 in the state of a speech so as to part the antenna 2 from a human body. A step difference 4 whose size is in matching with the size of the antenna 2 is formed and the support member 3 is contained in the case 1 in other cases than the speech, the antenna 2 is fitted to the step difference 4 to be integrated with the case 1 so as to make the terminal equipment convenient for carrying. Moreover, the patch conductor face on which a patch conductor 2a is placed in this state is located to an upper face of the case 1 and no hindrance is caused to communication.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile terminal device for satellite communication using a patch antenna.

[0002]

2. Description of the Related Art Conventionally, in satellite communication, a patch antenna for radiating circularly polarized waves in a vertical direction, in which a patch conductor is arranged on a dielectric (substrate) and a ground conductor is arranged under the dielectric (substrate), It is generally used.

[0003]

However, the patch antenna for satellite communication has a large shape, and unlike a small antenna such as a cellular phone or PHS, it is difficult to store it in the housing of a portable terminal device. is there. In addition, the patch antenna is susceptible to the surrounding environment and has extremely delicate characteristics. When touching the human body, the characteristics of the antenna change, so use the antenna away from the human body during a call. There is a need.

[0004]

According to the present invention, there is provided a patch antenna, a support means for supporting the patch antenna and capable of being housed in and retracted from a terminal housing, and the patch antenna when the support means is housed in the terminal housing. So that it has a step with which

Further, according to the present invention, the patch antenna is arranged at the upper end portion of the terminal housing, the microphone is arranged at the tip end portion of the flip rotatably supported at the lower end portion of the terminal housing, and the display portion is arranged above the terminal device. The ear speaker is arranged below the display section of the terminal housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 are respectively the first to the first of the present invention.
It shows a fourth embodiment, and the same reference numerals are given to the same portions in each drawing.

FIG. 1 is a satellite communication mobile phone showing a first embodiment of the present invention, wherein (a) is a perspective view when waiting for an incoming call, and (b) is a perspective view during a call.

The patch antenna 2 is arranged on the upper surface of the terminal housing 1, and is integrated with the terminal housing 1 as shown in FIG. 3A during standby and manually / automatically or directly by hand during communication as shown in FIG. As described above, the support member 3 to which the patch antenna 2 is attached is pulled out from the storage section in the terminal housing 1 to move the patch antenna 2 away from the human body. A step 4 matching the size of the patch antenna 2 is formed on the upper surface of the terminal housing 1, and the support member 3 is housed in the terminal housing 1 except during a call, and a patch is formed as shown in FIG. Antenna 2 with step 4
To be integrated with the terminal housing 1 to make it convenient to carry. In the state of FIG. 3A, the patch conductor surface on which the patch conductor 2a is arranged is on the upper surface side of the terminal housing 1, and does not hinder incoming calls.

FIG. 2 is a rear view of a satellite communication mobile phone showing a second embodiment of the present invention. (A) is a perspective view when waiting for an incoming call, and (b) is a perspective view when talking. It is a figure. In this example, the patch antenna 2 is rotatable in both directions with respect to the support means 3 as shown by the arrow. The rotation requires an angle switching mechanism such as a hinge, but the illustration is omitted. As shown in (a) of the figure, during standby,
In the step portion 4, the patch antenna 2 is substantially united with the patch conductor surface on which the patch conductor 2 is arranged facing the back side and the terminal case 1 and the terminal case 1 receives the call with the back side facing upward. Await. Alternatively, the patch antenna 2 may be rotated in the state shown in FIG. 3A, and the patch conductor 2a may be directed toward the upper surface of the terminal housing 1 to wait for an incoming call. When making and receiving calls,
The supporting means 3 can be manually or automatically or directly by hand as shown in FIG.
To make a call. Although the present example has a structure in which the patch conductor 2a is on the back side during standby, the present invention is not limited to this, and a step or the like is formed so that the patch conductor 2a faces the front side or the side surface. I don't mind.

3 (a) and 3 (b) are satellite communication mobile phones showing a third embodiment of the present invention. FIG. 3 (a) is a perspective view during standby and FIG. 3 (b) is a perspective view during communication. . Terminal housing 1
Display unit 9 is arranged on the upper front, and ear speaker 8
Are arranged in the central portion below the display unit 9. Further, it has a flip 6 for covering the ear speaker 8 and the operation section 10 thereunder, and at the time of a call, the flip 6 is opened by hand or directly by hand as shown in FIG. Patch antenna 2
Is fixed integrally with the step of the upper surface of the terminal casing 1, but since the ear speaker 8 is below the display unit 9, the patch antenna 2 is separated from the head by 1 inch or more in the talking state. It is not easily affected by the unit, and good satellite communication can be realized even with a small mobile terminal device. Note that, also in this example, the support means 3 to which the patch antenna 2 is attached may be drawn out similarly to the first embodiment shown in FIG. Also in this example, the patch antenna 2 may be configured to be rotatable as in the second embodiment shown in FIG.

FIG. 4 shows a fourth embodiment of the present invention. This example is an example in which a microphone 5 is attached to a stick-shaped flip 7, and the other points are the same as those of the third embodiment of FIG.

[0012]

As described above, according to the present invention, in a portable terminal device for sanitary communication using a patch antenna, the size of the terminal housing can be reduced, and moreover, the patch antenna can be separated from the head to talk.

Also, since the patch antenna is integrated with the terminal housing so as to be integrated, the large patch antenna does not get in the way when it is carried and the damage of the patch antenna can be prevented from being dropped or shocked, and the design is excellent. It will be a good thing.
