Abstract

(57) [Summary] (Modified) [Purpose] In this invention, an inductive resonance circuit is printed on a resin film. The present invention relates to a label antenna for a wireless communication device. [Configuration] Circuit A (2) on one side of film base (1)
And a circuit B (3) is printed on the opposite surface, and a resonance circuit is formed by using the film base (1) as a dielectric to form a single-label antenna.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a relay antenna for a wireless communication device such as a mobile phone, a car phone, a cordless phone, a personal handy phone, and an amateur radio.

[0002]

[Prior art]

 In the past, antennas were attached to both the outside and inside of the window glass, and cords (cables) were wired from the antennas to the wireless communication devices. When using a wireless communication device in a car, it had to be removed each time the car was washed, which was troublesome. I was afraid that the part outside the car was mischievous, stolen, or damaged. It was extremely difficult to install it on the outside of window glass that cannot be opened or closed, such as in high-rise buildings. It was difficult to reuse the type that uses adhesive glue because the trace of the glue would get dirty when it was removed and the antenna would be damaged.

[Problems to be solved by the device]

 This plan overcomes the drawbacks, does not bother the wiring cord, can be easily removed and reused, and can be safely installed only inside the window glass (inside or inside the vehicle) without the risk of theft or damage. It aims to develop a simple label-shaped antenna.

[0004]

[Means for Solving the Problems]

 The solution means will now be described with reference to the drawings. (A) In order to configure the induction resonance circuit of FIG. 1, the circuit A from one side (front) to the other side of the film base 1 as shown in FIG. Print the circuit B of 3 from (back) with aluminum or the like. (B) Circuit A 2 and circuit B 3 printed from both sides of the film base 1 form a resonance circuit of a capacitor coil using the film base 1 as a dielectric in the form of the completed drawing of FIG. With a single label, it functions as a complete group antenna. (C) By using a vinyl-based special resin for the film base 1, it can be attached to the window glass without the need to apply an adhesive or glue to the film base, and can be peeled off and reused many times.

[0005]

[Action]

 Since the present invention is configured as described above, by attaching a single label-like antenna from the inside of the window (inside the car or inside the room) to the window glass, it is possible to prevent radio wave attenuation of the wireless communication device and noise reduction measures. can do. Despite not using adhesive or glue, it does not fall off and can be peeled off easily without leaving any glue marks.

[0006]

【Example】

 In implementing the present invention, the following can be done. (B) By applying a special adhesive agent with low adhesive strength to the film base, it can be easily peeled off without peeling, and glue marks can be applied to window glass with unevenness or roughness such as makeup glass or cloudy glass. You can make a type that does not remain. It can be used on ordinary glass windows without any problems, and although it has a stronger sticking force than the glueless type, it can be peeled off as easily as a glueless type and can be reused as many times as necessary. (B) It can also be made by pasting cut aluminum foil instead of printing. (C) It is possible to design an inductive resonance circuit that suits the operating frequency band that differs depending on the type of wireless communication device, and create an antenna that suits each device. (D) As shown in FIG. 4, the film base 1 can be made on only one side (front side). In that case, the derivative of 4 is needed. There are various materials such as resin film, glass, acrylic plate, etc., but air may be used. The problem is that the area of the coupling part that forms the resonance circuit changes depending on the thickness, rather than the material.

[0007]

[Effect of device]

 The product of the present invention only needs to be attached to the inside of the window glass, not to the outside of the window, so it is particularly suitable and safe for high floors. There is no need for wiring cords, and even if peeled off, no glue marks remain and there is little annoyance. Since it is affixed inside the car or inside the room, there is no need for mischief or damage. It is an economical and convenient label-shaped antenna that is easy to remove and can be reused many times.
