Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a printed matter such as a poster, a calendar, and a wallpaper which is flexible and has an antenna function.

[Conventional technology]

Conventionally, various types of planar antennas that are flexible and have an antenna function have been proposed, but they only function as an antenna.

[Problems to be solved by the device]

However, printed materials such as posters and calendars,
If an antenna with an antenna that is barely noticeable in appearance is developed, the antenna can be used as an interior design article and is considered to be extremely useful.

Therefore, the problem to be solved by the present invention is to provide printed matter such as posters, calendars, and wallpapers having an antenna function that is inconspicuous in appearance.

[Means for Solving the Problems]

The present invention has been made for the purpose of solving the above-mentioned problems, and its structure is such that one or both sides of a sheet-shaped substrate made of a synthetic resin film, paper or the like has a pore diameter of 400 to 400 due to a conductive thin layer. An antenna pattern is formed by a large number of fine through holes of 500μ, line width of about 80μ, and aperture ratio of about 70%, and posters, calendars, paper walls, etc. with or without a synthetic resin layer or paper on one or both sides. It is characterized by being printed.

[Action]

The printed matter with the antenna function of the present invention can be hung on a wall surface in a room and connected with a lead wire at the end of the conductive thin layer.
Not only does it function as an invisible antenna, it is also an effective interior design product.

〔Example〕

FIG. 1 is an enlarged cross-sectional view of a printed material having an antenna function of the present invention, FIG. 2 is a front view of an example of a state before printing, and FIG.
The figure is also a partially enlarged perspective view, and FIG. 4 is a front view after printing.

In the figure, 1 is a sheet-like base material made of a synthetic resin film having a thickness of about 10 to 50 μm, 2 is a conductive thin layer laminated on the upper surface of the sheet-like base material 1 in an antenna pattern. The layer 2 is formed so as to function as an antenna. 2a is a fine through hole formed in the conductive thin layer 2 in a substantially uniform number. 3 is a lead wire connected to the conductive thin layer 2, 4 is an output terminal, 5 is an intermediate layer made of a synthetic resin film or the like laminated on the upper surface of the sheet-shaped substrate 1 including the conductive thin layer 2, and 6 is It is a printing layer applied on the intermediate layer 5, and thus constitutes one example of the printed matter of the present invention.

The printed matter having the antenna function of the present invention constructed as described above is manufactured by the following method.

That is, after applying a sizing agent on the upper surface of the sheet-shaped substrate 1 excluding the antenna pattern, a conductive metal such as iron is laminated on the entire surface by sputtering or the like, and then the sizing agent is removed.
The conductive metal layer laminated on the upper surface of the adhesive together with the adhesive while leaving the antenna pattern is removed, and the conductive thin layer 2 is formed on the portion of the antenna pattern.

The large number of fine through holes 2a of the conductive thin layer 2 forming the above antenna pattern are formed as follows.

That is, a transparent film sheet is used for the sheet-shaped substrate 1,
As shown in the enlarged view of FIG.
A large number of fine through holes 2a having a width of about 500μ and a line width of about 80μ are substantially evenly distributed in a state of being in contact with each other, and the conductive metal thin layer 2 formed on the antenna pattern having an aperture ratio of about 70% is provided. , The method for that is as follows.

Silver, copper, silver alloy, copper alloy,
Aluminum, tin oxide, etc. are laminated by means such as sputtering and vapor deposition, and the fine through holes are formed on the surface of this thin metal layer.
Similar to 2a, a colored photoresist resin film having a large number of fine through holes uniformly formed is adhered and laminated, and then the resin is cured by irradiating with ultraviolet rays, and then the fine through holes of the photoresist resin film are formed. The thin metal layer is subjected to etching to form fine through holes in the thin metal layer and the thin metal layer is formed into an antenna pattern, and then the photoresist resin layer is removed. The product obtained in this manner is directly or laminated on the intermediate layer 5 made of an appropriate synthetic resin or the like, and the printing layer 6 is formed thereon.

In addition, in the above, in order to form the conductive thin layer 2, a conductive metal is laminated by sputtering, but the metal may be vapor-deposited, and the antenna is directly attached to the sheet-shaped substrate 1 by the conductive ink. The conductive thin layer 2 may be formed by printing a pattern.

Further, although the conductive thin layer 2 is formed on only one side of the sheet-shaped substrate 1, the present invention provides the conductive thin layer 2 to the sheet-shaped substrate 1.
Alternatively, the print layer 6 may be provided on both sides.

The printed matter having the antenna function of the present invention constructed and manufactured as described above is printed on the printed layer 6 by overlapping the antenna pattern.
By printing images, patterns, etc. for posters, calendars, wallpapers, etc., it is possible to decorate the room as an interior design product of printed matter in which the antenna pattern is visually inconspicuous, and the thin conductive pattern formed on the antenna pattern is used. By connecting the lead wire 7 for an antenna of an electronic device or the like to the output terminal 4 of the layer 2, it can be used as a wide range of antennas for receiving FM broadcasting, TV broadcasting and the like.

In this case, as the antenna lead wire 7, a conductive thin layer 22 in which a large number of minute through holes 2a are arranged substantially uniformly in a row is formed on the sheet base material 11 in the same manner as the antenna pattern of the present invention. It is desirable to do. This is because it does not make the weight bulky and makes it inconspicuous in appearance.

[Effect of device]

The present invention is as described above, including a poster, a calendar,
If you print the wallpaper etc. and attach it to the wall in the room and connect the lead wire for the antenna of the electronic device etc. to the conductive thin layer, the antenna is not conspicuous and it is easy to use for interior design and it also functions as an antenna. It is extremely convenient, and at the time of manufacturing, it can be manufactured extremely easily and with high accuracy by applying a part of the technology such as manufacturing of printed wiring boards.

In addition, since the conductive thin layer in the printed matter of the present invention has a large number of fine through holes formed substantially uniformly, the weight of the printed matter can be reduced.
