TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for using an antenna device for a wireless network, an antenna device for a wireless network, and a computer device provided with the antenna device for a wireless network. More specifically, only the antenna device is moved outside the computer device to ensure directivity. The present invention relates to a method for freely using a wireless network antenna device, a wireless network antenna device, and a computer device having the wireless network antenna device.
[0002]
[Prior art]
Currently, a network (LAN or the like) that performs wireless communication without using a cable has become popular. This is very convenient irrespective of indoors and outdoors because it can access the Internet or a network (LAN or the like) without connecting to a cable. Nowadays, the number of places (restaurants, airports, etc.) where a wireless LAN called a hot spot can be used is increasing, and it is expected that it will be widely used in the future.
[0003]
As a conventional antenna, a dielectric antenna, an inverted-F antenna made of a metal plate, a substrate antenna, and the like have been used. The features of these antennas include miniaturization, omnidirectionality, and high gain. These antennas were mounted on the bottom and both sides of the notebook computer keyboard, near the hinge, or on the sides and top of the LCD, and their positions were always fixed. Further, a diversity system in which two antennas are mounted is generally used.
[0004]
Referring to FIG. For example, the antenna may be installed near the hinge of the notebook computer 51, below the keyboard of the main body 53, around the LCD 55, or the like.
[0005]
FIG. 4B shows the inside of the position CIR of the main body 53 in FIG. That is, the antennas 57 and 58 are provided at predetermined positions inside the main body 53. In each case, the antennas 57 and 58 are fixed with screws, adhesive tape, or the like, and are fixed so as not to move once mounted.
[0006]
[Problems to be solved by the invention]
Conventional derivative antennas, board antennas, inverted F antennas, and the like are all fixed inside the notebook computer with screws or double-sided tape, so that their positions cannot be moved. Therefore, the receiving direction (directivity) of the radio wave is always constant, and the receiving sensitivity of the radio wave may be low depending on the place where the notebook computer is used. In such a case, the direction of the notebook computer itself may be rotated, Had to be changed.
[0007]
As for the antenna, it is very difficult to design the antenna due to the installation position of other parts and the influence of radio waves, and the installation position has to be considered. Further, since the internal structure differs depending on the PC to be mounted, the antenna shape, material, and the like change, and the versatility is low.
[0008]
Also, PCI cards for wireless LAN are sold, and some do not have an antenna built into the computer itself. In this case, the card has an antenna, and the angle and direction of the antenna can be freely changed, so that the directivity is good. However, since the card is ejected from the computer device, it becomes a hindrance when using the computer device. Also, the use of a card occupies one slot provided in the computer device. When performing a wireless LAN, there is a problem that a PCI card must be separately purchased.
[0009]

[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0023]
Please refer to FIG. FIG. 1A shows a computer device 1 including a wireless network antenna device. The computer device 1 including the wireless network antenna device in the present example includes a computer main body 3, and the computer main body 3 includes a display unit 7 that can be opened and closed by a hinge. The computer body 3 is provided with a keyboard 5 and the like. That is, a notebook personal computer is assumed, but a laptop personal computer or a desktop personal computer may be used.
[0024]
On the other hand, the wireless network referred to as the wireless network antenna device 11 includes, for example, a wireless LAN, a wireless WAN, and the like. The wireless network antenna device includes an inverted F antenna, a substrate antenna, a film antenna, and the like. In this example, the description will be made assuming a film antenna.
[0025]
Referring to FIG. FIG. 1A is a diagram of the LCD cover 9 (hereinafter simply referred to as a cover) on the rear side of the display unit 7 as viewed from an arrow AR1 in FIG. For example, a cable hole 13 is opened near the center of the cover 9 on the rear side of the display unit 9, and a cable (for example, a coaxial cable for power supply, a coaxial cable; the same applies hereinafter) 15 attached to the antenna from the cable hole 13 is inserted inside. Connected to a connection unit (not shown, for example, a built-in MiniPCI card). Even if the film antenna 11 is taken out, there is no electrical danger such as electric shock, but the appearance is not good, so that it is hidden by a logo of a personal computer, for example. When not used, the film antenna 11 is installed near the center on the cover 9.
[0026]
FIG. 1C shows a case where the film antenna 11 is taken out and used. In this case, stable and high-speed communication is performed by pulling the film antenna 11 and pulling out the cable 15 from the cable hole 13 (this is the same usage method as the antenna of a mobile phone, and the antenna is moved when used). When not in use, it is in the same form as storing the antenna). Here, the cable 15 having a predetermined length has a length sufficient to move the film antenna 11 to an arbitrary position on the cover 9. This makes it possible to search for a place with good directivity in a wide range. Further, there is an effect that the film antenna 11 is easily fixed.
[0027]
The operation and the like of the computer device 1 including the film antenna 11 which is an antenna device for a wireless network will be described with reference to FIG.
[0028]
Referring to FIG. The cover 9 of the display unit 7 is provided with a cable hole 13 for inserting and removing a cable 15 connected to the film antenna 11. It is desirable that the position of the cable hole 13 is near the center of the cover 9. This is because the center position on the surface of the cover 9 is appropriate for use as a place where the film antenna 11 is installed. That is, the film antenna 11 can be moved and installed in the area of the cover 9 while minimizing the length of the cable 15 pulled out from the center position, and the functionality is excellent.
[0029]
The cable 15 has one end connected to the film antenna 11. In addition, the other end is wired to the inside ER of the display unit 7 through the cable hole 13. The internal ER is provided with a drum 17 for winding the cable 15 and a spring-type driving unit 19 for driving the drum 17 to rotate. After the cable 15 has been pulled out by a predetermined length, the cable 15 is fixed by a stopper (not shown) provided in the drive unit 19. Thereby, it can be prevented from being rewound by the drive unit 19. When the cable 15 is rewound, the cable 15 is pulled out once and detached from the stopper to be rewound. Accordingly, when the film antenna 11 is stored, the cable 15 is automatically wound around the drum 17 and can be easily stored.
[0030]
The cable 15 is connected to a connection unit (for example, a MiniPCI card) 21. As a result, only the film antenna 11 can be taken out, and can be moved to adjust the directivity.
[0031]
For example, in order to match the directivity of the transmitting / receiving unit 25 of the network and the film antenna 11, the film antenna 11 is pulled out from near the center 23 at the time of storage, and is moved and rotated in the directions of the arrows AR2, AR3, and AR4. Fix in a proper position of directivity.
[0032]
In the above description, a position with good directivity was searched by moving on the cover 9, but the position for fixing the film antenna 11 is not limited to the position on the cover 9. For example, it may be attached to a place remote from the computer device 1.
[0033]
A cross section AA ′ of the film antenna 11 will be described with reference to FIG. The film antenna 11 has a three-layer structure in which a conductive paste 29 is screen-printed on a dielectric film 27 and a dielectric film 31 is further adhered thereon. One of the features of the film antenna 11 is that it is extremely thin (less than one-fifth of a substrate antenna which is generally said to be thin). By taking advantage of this feature, it is possible to mount the film antenna 11 outside the computer device 1 without mounting the film antenna 11 inside the computer device 1. The dielectric film 31 is provided with an adhesive layer (for example, Velcro (registered trademark)) 33. Thereby, the film antenna 11 can be fixed to a position in the cover 9 having good directivity.
[0034]
FIG. 3 shows a mode of use of a wireless network antenna device (the film antenna 11 in this example). Referring to FIG. If the film antenna 11 is placed directly on the cover 9 of the display unit 7, the directivity changes greatly depending on the inclination of the display unit 7. Therefore, the antenna is of a diversity type, and the other antenna 35 is located inside the computer main body 3. Install at the hinge (this may be a conventional antenna). Thereby, even if the inclination of the display unit 7 changes, the directivity can be secured.
[0035]
Referring to FIG. One end of the cable 15 to which the film antenna 11 is connected is a male connector 37, and a female connector 39 is provided near the center of the cover 9. Connect when using. After use, the film antenna 11 is removed and stored. As a result, it is not necessary to store the film antenna 11 in the computer device 1 and space can be saved.
[0036]
The present invention is not limited to the above-described embodiments, but can be embodied in other modes by making appropriate changes.
[0037]
【The invention's effect】
As described above, according to the present invention, for example, it is possible to freely change the directivity of an antenna, and there is an effect that reception becomes easy.
[0038]
Further, by attaching the antenna to the outside of the computer device, there is an effect that the influence of the antenna from the outside (the cover of the display unit, other components, etc.) is reduced, and the degree of freedom in design is increased.
[0039]
And since it is attached to the outside of the computer device, it is possible to cope with various computer devices, and there is an effect that the cost can be reduced as a whole because of high versatility.
[0040]
Further, the use of the film antenna has an effect that operability such as moving and fixing is improved.
