Description

Antenna system for mobile communication repeater {Antenna system for Mobile communication Repeater}

The present invention provides a donor antenna unit for transmitting and receiving a signal to and from a base station, a coverage antenna unit for transmitting and receiving radio waves to and from a subscriber station, and amplifying unit for smooth mobile communication service in a communication shadow area. And an antenna system for a mobile communication relay having an integrated power supply unit.

In general, a mobile communication service system includes a base station, a relay system, and a subscriber station, and the relay system includes a donor antenna unit, a repeater, and a coverage antenna unit.

In the mobile communication service system as described above, the base station and the subscriber station communicate in a constant frequency band, and each base station has a constant communication radius. Therefore, by arranging a plurality of base stations appropriately so that the communication radius of each base station overlaps with each other, the communication area can be expanded.

However, even if the entire city is covered by the arrangement of such a plurality of base stations, the signal is weakened as the signal transmitted from the base station propagates in the air, and thus, the mountain, the building, the basement of the building, the tunnel or the inside of the building, etc. Due to the same natural and artificial obstacles, the signal strength becomes weaker, resulting in a partial communication shadow area that prevents smooth reception of the subscriber station.

In order to solve the problem of the communication shadow area generation, a repeater including a donor antenna unit that can transmit and receive signals to and from the base station and a coverage antenna unit that can transmit and receive signals to and from the subscriber station is conventionally installed, The donor antenna unit and the coverage antenna unit were relayed by a repeater to realize mobile communication in a communication shadow area.

Hereinafter, a conventional mobile communication relay system will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of a conventional mobile communication relay system.

Referring to FIG. 1, a signal transmitted from a base station 104 is weakly received by a donor antenna unit 100 that propagates in air and transmits and receives radio waves to and from the base station 104.

Therefore, in order to enable smooth communication in the subscriber terminal 105, the weakly received signal is transmitted to the repeater 102 through the donor antenna unit 100 side signal transmission cable 103a, and an amplifier (not shown). Repeater 102 including a) amplifies the weak reception signal.

Next, the signal amplified by the repeater 102 is transmitted to the coverage antenna unit 101 which transmits and receives to and from the subscriber station 105 via the signal transmission cable 103b of the coverage antenna unit 101, and the coverage antenna unit 101. ) Transmits a signal to subscriber station 105.

In addition, when the subscriber station 105 sends a signal to the base station 104, the signal is transmitted in a path opposite to the above.

However, in the conventional mobile communication relay system as described above, the long signal transmission cables 103a and 103b for connecting the donor antenna unit, the repeater, and the coverage antenna unit and power lines (not shown) for supplying power to the repeater must be installed. Owing to its own transmission loss due to the signal transmission cables 103a and 103b, the installation cost is high, the installation and maintenance is difficult, and the aesthetics are bad.

Furthermore, there are many difficulties in relaying signals by connecting the signal transmission cables 103a and 103b only for a small space where the shadow area is not wide, such as the interior of an apartment.

Accordingly, an object of the present invention is to provide an antenna system for a mobile communication relay that can serve as a mobile communication relay in a radio shadow area at a low cost.

Another object of the present invention is to provide an antenna system for mobile communication relay that is easy to install and maintain and has a good aesthetic appearance.
