Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to an antenna installed indoors in mobile communication, wireless LAN, and the like.

[0002]

[Prior art]

 Conventionally, as an antenna for mobile communication systems used indoors, an antenna such as a ceiling mount type has been proposed in consideration of the installation location and the like, and the antenna has been formed in a shape suitable for the installation conditions.

[0003]

[Problems to be solved by the device]

 However, with this conventional antenna, there are strong demands for thinning and miniaturization in order to improve the installation property, and it has been relatively difficult to obtain the desired characteristics in order to satisfy this requirement. An object of the present invention is to provide an indoor installation antenna that is installed indoors and has desired characteristics and functions without being restricted by its installation property.

[0004]

[Means for Solving the Problems]

 In this invention, a container made of a dielectric is composed of a bottom plate, a cylindrical peripheral wall, and an insole that divides the inside into upper and lower parts, and an antenna element housing portion is provided between the bottom plate and the insole. The antenna element is housed in the housing portion. Various kinds of things can be stored in the upper part of the inner bottom of the container, and for example, soil can be cultivated such as foliage plants.

Alternatively, a lid that can be opened and closed is attached to the upper part so that it can be used as an interior for a room in which various items are stored in the upper storage part.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a preferred embodiment of the present invention will be exemplarily described in detail with reference to the drawings. (First Embodiment) FIG. 1 shows an embodiment of an indoor installation antenna of the present invention. In this embodiment, the container 11 has a cylindrical peripheral wall 13 which is integrally erected on the bottom plate 12 so that one end face is closed by the bottom plate 12, and the space formed by the bottom plate 12 and the peripheral wall 13 is vertically moved by the insole 14. Two minutes. The insole 14 is integrated with the peripheral wall 13, and the container 11 is made of a dielectric material, that is, a synthetic resin material, a reinforced plastic, a ceramic or the like, which is a material that transmits radio waves and has some mechanical strength. In this example, the peripheral wall 13 has a cylindrical shape.

A space between the bottom plate 12 and the insole 14 is an antenna housing portion 15, and the antenna housing portion 15 houses the antenna element 16. In this example, as the antenna element 16, a monopole antenna is erected on the center of the bottom plate 12. The storage 17 on the insole 14 is filled with soil 18, and the ornamental plant 19 is planted in the soil 18. A hole 21 for drainage is formed in the insole 14, and one end of a drainage pipe 22 is connected to the hole 21. The drainage pipe 22 passes through the inside of the antenna accommodating portion 15 and is provided on the peripheral wall 13. It has a structure that is communicated with the hole 23 for drainage. Further, a hole 24 for passing a connector for feeding power to the antenna element 18 or a cable for feeding power is provided in the lower portion of the peripheral wall 13. Further, if necessary, a hole 25 for draining water is also provided in the lower portion of the antenna housing portion 15, that is, the bottom plate 12. (Second Embodiment) FIG. 2 shows another embodiment of the present invention, in which parts corresponding to those in FIG. 1 are designated by the same reference numerals.

In this embodiment, nothing is placed in the upper accommodation portion 17 of the container 11, and the upper accommodation portion 17 is used for accommodating small items as needed. (Third Embodiment) FIG. 3 shows still another embodiment of the present invention. In this embodiment, a patch antenna (strip antenna) 28 is rotated in the antenna housing portion 15 with the plate surface vertical to the bottom plate 12. This is the case when it is set up freely. (Fourth Embodiment) FIG. 4 shows still another embodiment of the present invention. In this embodiment, the container 11 has a rectangular parallelepiped shape, and a lid 29 for opening and closing the upper surface of the peripheral wall 13, that is, the upper accommodating portion 17. Is installed. (Fifth Embodiment) FIG. 5 shows still another embodiment of the present invention, in which the peripheral wall has a hexagonal tubular shape, and other parts are designated by the same reference numerals as those corresponding to the previous embodiment. .

[0009]

[Effect of the invention]

 As described above, according to the present invention, an antenna having desired characteristics can be easily installed indoors because it is not particularly required to be small or thin, and the antenna element is housed in the container 11. In addition, since the accommodating portion 17 is provided at the upper portion, it is used for indoor ornaments, decorations, etc., and is comfortable for indoor installation.
