ある。In the antenna of this configuration, it is necessary to equip the antennas by the number of service areas covered by the base station. Therefore, when there are many service areas in charge, the installation area of the antenna becomes large,
It is an obstacle to configuring the base station. In particular, in the case of adopting the reception diversity method, it is necessary to install antennas more than twice the number of service areas, and there is a problem that the installation location of the antenna is largely restricted. An object of the present invention is to provide a base station antenna which eliminates obstacles in constructing a base station due to an increase in the number of antennas and also relaxes restrictions on the installation location of the antennas.

Is a perspective view and (b) is a plan view. Note that this embodiment shows an example in which the antenna is applied to the base station antenna ANT1 of the 3-sector cell system. In the figure, the reflector 2 is composed of three reflectors 3, each of which has a mutual central angle of 120.
It is integrated in the central part so that it becomes °. These reflectors 3 allow the radio waves to be reflected on both sides thereof. Further, here, the central portion of each reflection plate 3 may be formed in a triangular tube shape, and this portion may be connected to an antenna mast (not shown). Then, a total of three radiators 1 are integrally attached to the central portion of each reflector 3.

Therefore, in this embodiment, the configuration is equivalent to that in which three 60 ° beam corner reflector antennas are integrated at a central angle of 120 °. Therefore, as shown in FIG.
If the antennas are installed in the base station so that the radiators 1 of the NT1 face the three service areas SA, it becomes possible to construct an antenna equivalent to that shown in FIG. 5 using three conventional antennas. This can reduce the number of antennas,
It is possible to ease restrictions on the installation location of the antenna and solve obstacles in configuring the base station.

テナとして適用することができる。FIG. 3 is a perspective view of another embodiment of the present invention. Here, the planar reflection plate 3A is formed in a triangular tube shape to form the reflector 2A, and the radiator 1A is arranged in front of each reflection plate 3A. Then, the mast 4 is inserted through the central position of each reflector 3A, and the reflector 2A is fixed to the mast 4 by the support arm 5. In this configuration,
By changing the characteristics of the radiator 1A, the antenna can be configured as an antenna having various beam widths such as a 120 ° beam. Also in this configuration, one antenna can provide a function equivalent to that of three antennas, and the problem of antenna installation in the base station can be solved. The antenna of the present invention can be applied not only to the three-sector cell type but also to other sector cell type base station antennas by appropriately changing the number of reflectors and the angle.
