Abstract

PURPOSE: To eliminate a need of the drilling construction of a wall or the like and the maintenance of a device and to perform the communication to adjacent rooms without consuming the power for communication backup by connecting a reception antenna, an antenna coupling means, and a radiation antenna by a conductor. CONSTITUTION: The device consists of at least one reception antenna 22 for radio wave reception, an antenna coupler 23 for coupling or reception antennas 22, a radiation antenna 25 for radio wave radiation, ana a conductor 26 connecting the reception antennas 22, the antenna coupler 23, and a radiation antenna 25. Radio waves transmitted through a building member 21 are received by reception antennas 22 and are collected into one by the coupler 23 and are radiated again by the radiation antenna 25. Thus, radio waves of weak energy coming through the building member 21 are acquired by an equivalently large- area antenna 22 and are radiated again by the locally existing antenna 25 for reradiation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to communication using radio waves.

[0002]

2. Description of the Related Art Generally, only a relatively small electric power is legally permitted for radio waves used indoors for data communication between computers.

Therefore, when communication is performed between adjacent rooms, a communication failure is likely to occur because the amount of radio waves transmitted through walls, ceiling, floor, etc. is small.

FIG. 3 shows a conventional communication support device.

In FIG. 3, reference numeral 1 is a ceiling, a wall and a floor.

Reference numeral 2 is a receiver, 3 is a transmitter, 4 is a cable connecting the receiver and the transmitter, 5 is an information transmitter for transmitting information by radio waves, and 6 is an information receiver for receiving information.

As shown in FIG. 3, conventionally, the radio wave transmitted from the information transmitter 5 is once received by the receiver 2, guided to the next room by a cable, retransmitted by the transmitter 3, and then the information is transmitted. It was received by receiver 6.

[0008]

However, in the above-mentioned conventional example, unless a receiver and a transmitter for communication support are used, the spatial energy density of the radio wave transmitted through the wall surface is low, so that it is difficult to capture the radio wave. there were.

Further, when the communication support device is used, construction work such as making a hole in the wall surface for installing the cable is required and the construction cost is high, and there are problems such as maintenance of the communication support device and power consumption.

[0010]

In view of the above problems, at least one receiving antenna for receiving radio waves, and an antenna coupler for coupling the receiving antenna,
By providing a communication support device including a radiation antenna that radiates radio waves, and a lead wire that connects the reception antenna, the antenna coupler, and the radiation antenna, there is no need to construct a hole in a wall or perform maintenance of the device. Also, communication to an adjacent room can be easily performed without consuming electric power.

In FIG. 1, 7 is a communication support device,
The other parts are the same as those in FIG.

FIG. 2 is a block diagram showing the communication support apparatus of this embodiment.

In FIG. 2, reference numeral 21 is a building member such as a wall surface, a ceiling or a floor surface. Reference numeral 22 denotes a plurality of receiving antennas installed on the member 21. Reference numeral 23 is an antenna coupler that couples the receiving antenna 22 with a conductive wire. Two
Reference numeral 4 is a conductor connecting the receiving antenna 22 and the coupler. Two
Reference numeral 5 is a radiation antenna. Reference numeral 26 is a conductor connecting the radiation antenna 25 and the coupler 23. The receiving antenna 22 and the radiating antenna 25 may be any antenna that can be installed on the member 1. The receiving antenna 22 may be any antenna as long as it receives a frequency suitable for the purpose of use.

Further, in the present embodiment, 21 is a building member, but the present invention can also be applied to wallpaper, carpets, tapestries, wall hangings, etc. that do not have walls, ceilings, floors and the like.

In FIG. 2, the radio wave transmitted through the member 21 is received by the receiving antenna 22 and is transmitted by the coupler 23.
They are combined into one and re-radiated by the radiation antenna 25.

As described above, according to the present invention, a weak energy radio wave transmitted through the member 1 is equivalently captured by a large area antenna and re-radiated by a localized re-radiating antenna.

It is to be noted that the receiving antenna 22 having a directivity with respect to the member 21 is more likely to receive a radio wave other than the radio wave transmitted through the member 21, so that the sensitivity can be improved.

It is also possible to give the radiation antenna 25 directivity.

Further, the information receiver 6 can aim the re-radiating antenna 25 spatially with a directional antenna or the like.

Further, in this embodiment, the communication support device 7 is installed in the reception side room, but by installing the communication support device 7 in the transmission side room, the transmitted radio waves are put together into one member 21. May be transmitted.

[0023]

As described above, according to the present invention, there is no need to perform hole construction on a wall or the like and maintenance of the device,
To facilitate communication to an adjacent room without consuming electric power for supporting communication.
