Abstract

PROBLEM TO BE SOLVED: To prevent the breakage of an antenna element when a construction material is nailed to a building by forming the nail holes with avoidance of the antenna element to a construction material stuck by the antenna sheets containing the antenna element to attach the construction material to the building. SOLUTION: A TV receiving antenna element 11 is placed between two antenna sheets 12 made of plastic films to construct an an antenna main body 37. The body 37 is stuck on the lower surface of a roof material, i.e., a construction material by an adhesive or a double-sided adhesive tape, etc., via one of both sheets 12. Plural nail holes 31 are formed to the roof material with avoidance of the element 11 of the body 37 to attach the roof material to a roof board. At the same time, the nail holes 32 are formed to the body 37 against the holes 31. Thus the roof material stuck by the body 37 can be easily and surely attached to a building via those holes 31 (32).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving planar antenna device in which an antenna element is integrally incorporated into a building material such as a roof material or an outer wall material.

[0002]

2. Description of the Related Art An antenna element for TV reception is installed on a roof in order to prevent the appearance of a building from being damaged and damage or radio interference caused by external factors such as wind and rain. 2. Description of the Related Art There has been proposed a planar antenna device for reception, which is integrally incorporated in a building material such as a building material or an outer wall material.

In this type of conventional receiving planar antenna device, an antenna element is provided by applying a conductive paint or pasting a conductor such as a conductive tape onto an antenna sheet made of a plastic film to form an antenna body. Then, the antenna body is attached to the lower surface of the roofing material (for example, Japanese Patent Laid-Open No. 7-106846).

[0004]

However, in the conventional case,
When the roof material with the antenna main body attached is attached to the base plate with nails, if the nails are inadvertently hit, the antenna elements or the power supply lines for coupling for connecting multiple antenna elements may be damaged by the nails. It was In view of the above problems, the present invention is intended to prevent the antenna element from being damaged by the nail when the building material such as the roof material to which the antenna body is attached is nailed to the building side such as the ground plate. .

[0005]

The technical means of the present invention for solving this technical problem is that an antenna main body 37 in which an antenna element 11 is provided on an antenna sheet 12 is a roof member 39 or an outer wall member 51. In the planar antenna device for reception attached to the building material, a nail hole 31 for attaching the building material to the building side is provided in the building element.
The point is to avoid 1.

Therefore, by using the nail holes 31 of the building material, the building material such as the roof material 39 or the outer wall material 51 to which the antenna body 37 is attached can be easily and surely attached to the building side. At this time, since the nail hole 31 is located away from the antenna element 11, the nail 33 is driven into the antenna body 37 at a location away from the antenna element 11.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the illustrated embodiments. 1 to 3, reference numeral 11 denotes a TV receiving antenna element, which is arranged between two antenna sheets 12 made of a plastic film. That is, the antenna element 11 is formed by applying a conductive paint or pasting a conductor such as a conductive tape on the surface of the one antenna sheet 12, and sandwiching the antenna element 11 in the one antenna sheet 12 in a sandwich shape. Thus, the other antenna sheet 12 is polymerized, and the antenna sheets 12 are adhered to each other with an adhesive.

The antenna element 11 has a pair of side portions 15, another side portion 16 and a pair of power feeding side portions 17 which project inward from one end of the pair of side portions 15. A pair of power supply sides 17
A pair of feeding points 18 are installed at opposite ends of the. A bent portion 21 is interposed between the pair of side portions 15 of the antenna element 11. The bent portion 21 has a characteristic similar to a linear side portion obtained by linearly extending the bent portion 21, and can be replaced with a long straight side portion of the antenna element 11. Therefore, by interposing the bent portion 21 between the pair of side portions 15, the pair of opposing side portions 15 of the antenna element 11 is formed to be short, so that the entire size of the antenna element 11 can be reduced to the size of a unit building material such as a roof material. It is possible to shorten the length and integrate the antenna element 11 with a unit building material such as a roof material.

A cable is connected to the feeding point 18 of the antenna sheet 12, and the antenna element 11 is connected to the receiver via the cable. The antenna element 11, the two antenna sheets 12, and the like form an antenna body 37.
It is attached to the lower surface of the roof material 39 with an adhesive or a double-sided adhesive tape 38 or the like via the one antenna sheet 12, whereby the antenna element 11 is integrally incorporated in the roof material 39 which is a building material.

The roof member 39 is provided with a plurality of nail holes 31 for attaching the roof member 39 to the base plate 41 so as to avoid the antenna element 11 of the antenna body 37. Further, a nail hole 32 is provided in the antenna body 37 so as to correspond to the nail hole 31 of the roof material 39. As shown in FIG. 4, the roofing material 39 to which the antenna main body 37 is attached is placed together with another roofing material 39 on a roof plate 41 through a waterproof sheet 42, and the roofing material is fixed by a nail 33. It is struck on the base plate 41 through the nail holes 39 of the antenna body 37 and the antenna body 39.

1 is provided as a pair, and the pair of antenna elements 11 are connected to each other by a pair of feed lines 44 for coupling, and a feed point 18 is installed in the middle of the feed line 44 for coupling. A cable is connected to the feeding point 18, and each antenna element 11 is connected to the receiver via the cable. The coupling feed line 44 is formed by applying a conductive paint or pasting a conductor such as a conductive tape on the surface of the antenna sheet 12 as in the case of each antenna element 11. Other configurations are the same as those in the above-described embodiment, and the roof material 39 has a plurality of nail holes 31 for attaching the roof material 39 to the base plate 41 so as to avoid the antenna element 11 of the antenna body 37. It is provided. Further, a nail hole 32 is provided in the antenna body 37 so as to correspond to the nail hole 31 of the roof material 39.
