Abstract

(57) [Abstract] [Purpose]
For example, in a base station where a large number of transmitters are installed indoors with a relatively small output of 10 mW, such as andy Phone System), a flat antenna is arranged in a frame having a decoration such as a painting or a photograph, and the indoor appearance is improved. The present invention relates to an indoor antenna that does not damage the. [Construction] In the indoor antenna of the present invention, a coaxial cable 3 is connected to a coaxial connector 2 provided on a patch antenna 1. The patch antenna 1 is housed in the frame 12,
A decoration 13 such as a painting or a photograph is arranged on the front surface of the frame 12, and the frame is hung on the wall with a string or the like. The high frequency signal supplied from the coaxial cable 3 is radiated forward from the patch antenna 1 and radiated indoors without being attenuated.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention is a base station installed indoors with a relatively small output of 10 mW, such as a PHS (Personal Handy Phone System), in which a flat antenna is arranged in the frame of a painting or a photograph. The present invention relates to an indoor antenna that does not spoil the aesthetics indoors.

[0002]

[Prior art]

 FIG. 2 is a diagram showing a configuration of a conventional patch antenna, where 1 is a patch antenna, 2 is a coaxial connector, 3 is a coaxial cable, and 11 is a radome. Next, the operation will be described. The conventional patch antenna 1 is housed in a plastic case such as the radome 11, the coaxial cable 3 is connected to the coaxial connector 2, and the patch antenna 1 is fixed to a wall or a pillar with a mounting bracket or the like. For this reason, there was an aesthetic problem when it was installed in the shop.

[0003]

[Problems to be solved by the device]

 Since the conventional indoor antenna is stored in a plastic case such as a radome, it has an aesthetic problem and must be installed in an inconspicuous place such as in the shade of the structure to ensure the desired directivity. Was difficult. This invention was made in order to solve the above problems, and is to solve the aesthetic problem by arranging a decoration such as a picture or a photograph on the front surface of the patch antenna. .

[0004]

[Means for Solving the Problems]

 The invention according to claim 1 is characterized in that a decoration is arranged on the front surface of the planar antenna. The invention of claim 2 is characterized in that the planar antenna is integrated with high-frequency equipment such as a base station.

[0005]

[Action]

 According to the device of the first aspect, the aesthetic appearance can be maintained even when installed indoors. According to the invention of claim 2, since the indoor antenna is integrally formed with the base station or the like, a small-sized base station can be realized.

[0006]

【Example】

 An embodiment of this invention will be described below with reference to the drawings. In FIG. 1, 1 is a patch antenna, 2 is a coaxial connector, 3 is a coaxial cable, 12 is a frame, and 13 is an ornament. Next, the operation will be described. The coaxial cable 3 is connected to the coaxial connector 2 provided on the patch antenna 1. The patch antenna 1 is housed in a frame 12, and the frame 12 is hung on a wall with a string or the like. The high frequency signal supplied from the coaxial cable 3 is radiated forward from the patch antenna 1 and radiated indoors without being attenuated. Since the ornament 13 is arranged on the front surface of the indoor antenna, it does not spoil the aesthetic appearance even if it is installed indoors.

In the above description, the case where the patch antenna is used as the plane antenna has been described, but the same effect can be obtained by using other plane antennas. The same effect can be obtained regardless of whether the frame material is metallic or non-metallic. Similar effects can be obtained even if the planar antenna has an integrated structure including the high frequency device of the base station.

[0008]

[Effect of the invention]

 According to the invention as set forth in claim 1, it is possible to realize an indoor antenna that is installed indoors and does not spoil the appearance. According to the invention of claim 2, it is possible to realize a small base station integrated with an indoor antenna.
