PROBLEM TO BE SOLVED: To provide a base station antenna device that is able to improve frequency utilization efficiency.SOLUTION: Each sector antenna 2 is configured to be able to communicate at a plurality of frequencies at the same time, and also to be able to communicate in different directivity per frequency. A signal control unit 3 comprises: a terminal positional information management unit 19 which manages terminal positional information on a terminal situated in a cell; a channel information unit 20 which divides each sector into a plurality of areas having different allocation frequencies, and determines an allocation frequency depending on an area where a terminal to be a communication object is situated; a directivity control unit 21 which controls the directivity of the sector antenna 2; and a scheduler 22 which controls the sector antenna 2 such that a frequency used when performing communication with the terminal to be the communication object will be the allocation frequency determined by the channel information unit 20, and also controls the sector antenna 2 such that the directivity of a frequency used for communication will be directed to the terminal to be the communication object. |
