Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure which also serves as a receiving antenna.

[0002]

2. Description of the Related Art Hitherto, as a television receiving antenna, an antenna having a receiving element has been raised above a roof of a house via a pole.

[0003]

However, the construction of the receiving antenna via the pole as described above has a drawback that the appearance of a building such as a house is greatly deteriorated. In addition, the pole becomes quite heavy in order to obtain the antenna support strength, and there is a problem that the roof tile is cracked or broken due to its weight, and when installing the antenna, give due consideration to the strength of the roof tile, etc. Erecting an antenna had the disadvantage of requiring cumbersome measures. Further, the antenna may fall down due to a strong wind such as a typhoon, and there are various disadvantages such as damaging the antenna itself as well as surrounding roof materials when the fall occurs.

[0004] On the other hand, in order to solve such a problem, the inner and outer surfaces of a wall surface which does not include a metal material are used.
It is conceivable to attach a waveguiding element on the outer surface and a resonance element on the inner surface to receive radio waves.However, in this case, if the wall surface is just perpendicular to the direction of radio waves arrival, there is no problem. In other cases, however, there was a drawback that the reception gain was not obtained and only insufficient reception was possible.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention has a receiving antenna for a television or the like which has no influence on the appearance of a roof, has a troublesome measure for supporting strength, and has a reception without a risk of falling. An object of the present invention is to provide an antenna and a wall structure which also serves as a receiving antenna capable of providing a sufficient receiving gain in any direction of arrival of radio waves.

[0005]

That is, the wall structure 1 also serving as a receiving antenna according to the present invention has an inner wall material 3 on the indoor side and an outer wall material on the outdoor side of the wall support structure 2 arranged so as not to be orthogonal to the radio wave arrival direction. In the wall structure 1 to which the outer wall member 4 is attached, the waveguide elements 5 and 5 are provided on the indoor side surface 4A of the outer wall member 4, and the resonance elements 6 and 6 and the conducting wires 7 and 7 for guiding the electric potential are provided on the inner wall member 3 outdoor side surface 3B. And the waveguide elements 5, 5
The positional relationship between the two and the resonance elements 6 and 6 is regulated so that the line of sight between them and the line of sight coincide with the direction of arrival of radio waves.

[0006]

In the present invention, incoming radio waves are received by the waveguide elements 5, 5 and the resonance elements 6, 6 attached to the respective surfaces of the inner wall material 3 and the outer wall material 4 constituting the wall surface of the building. However, the positional relationship between the waveguide elements 5, 5 and the resonance elements 6, 6 is regulated so that the line of sight coincides with the radio wave arrival direction (arrow X).

Therefore, even if the wall surface is not perpendicular to the radio wave arrival direction, it is sufficient if the mutual line of sight between the waveguide elements 5, 5 and the resonance elements 6, 6 coincides with the radio wave arrival direction. A good reception gain. Then, the radio waves received in this manner are guided to the receiving device by the conductors 7, 7. Further, the directivity of the resonance elements 6, 6 provided on the outdoor side surface 3B of the inner wall material 3 is improved by the waveguide elements 5, 5 provided on the indoor side surface 4A of the outer wall material 4, and the reception gain is improved. You.

Next, an embodiment of the present invention will be described. 1 is a sectional view of an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a sectional view taken along line BB of FIG.

The wall structure 1 which also serves as the receiving antenna of the present invention.
Is an inner wall material 3 on the indoor side and an outer wall material 4 on the outdoor side of a wall support structure 2 comprising support columns 2A and a rim 2B, etc., which are wall surfaces which are not arranged orthogonally to the direction of arrival of radio waves in a building. Side wall 4A of the outer wall material 4
As shown in FIG. 2, the waveguide elements 5 and 5 are provided, and the resonance elements 6 and 6 and the conducting wires 7 and 7 for guiding the electric potential are provided on the outdoor side surface 3B of the inner wall member 3.
The positional relationship between the two and the resonance elements 6 and 6 is regulated so that the line of sight between them and the line of sight coincide with the radio wave arrival direction (arrow X).

In the above embodiment, reference numeral 4B denotes a wall base material and 4C denotes a waterproof paper. The wall support structure 2 is made of wood, and the inner wall material 3 and the outer wall material 4 are each made of a wall plate that does not include a metal reinforcing material such as a reinforcing steel bar. The waveguide element 5, the resonance element 6, and the conducting wire 7 for conducting the electric potential are all made of a conductive metal foil or a thin metal plate, and these elements are integrated with an adhesive sheet (not shown). To be adhered to a predetermined surface of the inner wall material 3 or the outer wall material 4 as necessary.

The wall structure 1, which also serves as a receiving antenna, is connected to the wave-receiving side of the building, in the direction in which the transmitting antenna can be seen, by the waveguide elements 5, 5 and the resonance elements 6, 6.
Adjust the line of sight with the actual reception level from 400MHz to 800M
When measured over Hz, the data shown in FIG. 4 was obtained. For comparison, the reception level was compared with the reception level by the Yagi antenna, but it was confirmed that the reception level was slightly inferior, but had little effect on actual reception.

[0012]

[Effects of the Invention] As described above, according to the wall structure of the present invention which also serves as the receiving antenna, since the building wall also serves as the receiving antenna as it is, there is no need to particularly provide an antenna on the roof. And the various adverse effects when the receiving antenna is erected on the roof are completely eliminated, and even if the wall surface is not orthogonal to the radio wave arrival direction, the waveguide element 5 and the resonance element 6 If the line of sight is matched with the direction of arrival of radio waves, a sufficient reception gain can be obtained, and various practical effects such as easy implementation can be obtained.
