Abstract

PURPOSE:To obtain an antenna which can be set in a room and has a high sensitivity and is easy to attach, by sticking an adhesive to one side of an antenna element and adhering it to a ceiling, a wall, or the like. CONSTITUTION:An antenna element 6 having an adhesive, for example, a pressure-sensitive adhesive on one face is adhered to a ceiling surface 7 in a room, and the antenna element 6 is connected to a television 9 from the ceiling surface 7 by a coaxial cable 8; or the antenna element 6 is adhered to a wall surface 10 in the room and is connected to an FM receiver 12 from the wall surface 10 by a feeder line 11. Thus, dimensions and th shape of the antenna element can be changed to enhance the sensitivity because it is adhered to the surface of a ceiling, a wall, or the like. Since the antenna element is attached with the adhesive, it is easy to attach the antenna element.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a high-sensitivity instant antenna characterized in that an adhesive is attached to one side of an antenna element, and the adhesive part is attached to a ceiling, wall, etc., and can be installed indoors. An antenna with high sensitivity and easy installation can be obtained.

Conventionally known antennas for televisions, etc. include, for example, an indoor antenna 2 that can be placed on top of the television 1 as shown in Figure 1, but if it were made too large, it would get in the way, so it was made small, and the sensitivity was low and good images could not be obtained. I couldn't.

Furthermore, as shown in Figure 2, even though the antenna 4 has a high sensitivity, it is not easy to install, and the antenna 4 has poor image reception when exposed to wind, is easily toppled over, and is prone to salt damage near the coast. The disadvantage is that the TV screen becomes invisible due to the

The parabolic antenna or area type antenna 5 as shown in FIG. 3 is also supported by a support rod 3, which is bulky, and the positions where it can be placed are limited.

The present invention solves these drawbacks of conventional antennas.

In the embodiment of the present invention, as shown in FIG. 4, the antenna element 6 itself is glued to the indoor ceiling surface 7, and then connected to the television 9 with a coaxial cable 8, or as shown in FIG.
An antenna element 6 is glued to an indoor wall surface 10 and connected to an indoor FM receiver 12 via a feeder line 11.

6 to 8 show embodiments of the present invention of an FM antenna, as shown in FIG. 6, the parallel two-core wire 13 coated with insulation has a T-shape as a whole between the terminal portions 14, and the core wire 15 is connected to the terminal 16.
They are connected to form a single line between them. These parallel two-core wires may be made by etching a copper-clad laminate.

Terminal 16 is connected to an FM receiver or television.

FIG. 7 is a view of this as seen from the cross-sectional direction, with the bonded portion being particularly enlarged.

There is a pressure-sensitive adhesive part 17 on the back side of the terminal part 14 for attaching it to a ceiling, wall, etc., and this adhesive part is coated with a pressure-sensitive adhesive layer 18 and a cushioning material 1 such as foamed polyurethane from the terminal part surface.
9. A pressure-sensitive adhesive layer 18 and a release liner 20 are laminated in this order, and as shown in FIG. The antenna element 6 can be fixed to a ceiling surface 7 or the like. At this time, even if there are irregularities 21 on the ceiling surface, the adhesive surface of the terminal portion 14 is brought into close contact with the adhered surface due to the deformation of the cushion material 19, and is sufficiently adhered.

9 and 10 show an embodiment of the present invention of a television antenna, in which the conductor 22 of the waveguide section, the conductor 23 of the feeding section provided with the terminal 16, and the conductor 24 of the reflecting section are spaced apart and pasted at L2. These conductors can be made by etching 1iIN formed on the surface of the base 25 made of plastic or the like, and applying pressure-sensitive adhesive Fi18 to the back surface of the base 25, or flat parallel two-core wires, coaxial two-core wires, etc. Alternatively, the pressure sensitive adhesive layer 18 may be provided on the aluminum sheet 26.

In the embodiment of the present invention shown in FIG. 11, the antenna element is an electric wire or a pipe 27, and a pressure-sensitive adhesive layer 17 is provided at both ends of a sheet 28 that straddles this, thereby holding the electric wire 27 and fixing it to the ceiling, etc. It is.

12 and 13 also show the aluminum sheet 26 according to the embodiment of the present invention.
Adhesive layer 1 is applied to a part of the back side, for example, corner 29 or the entire surface.
8. A cushion material 19, an adhesive layer 18, and a release liner 20 are laminated together.
Figure 3 is an enlarged side view. By attaching this to a wall, etc., you can obtain an inexpensive, compact, and highly sensitive antenna for new media such as satellite reception. Since the present invention is an antenna that is adhered to surfaces such as ceilings and walls, it can be made sufficiently large or changed in shape to increase sensitivity. Moreover, it does not get in the way indoors, can be easily installed, and has no effect on wind and rain. This is an invention that has many significant benefits, including low cost.

All other changes in materials and shapes of the above embodiments are included in the present invention.
