摘要： The present invention is an antenna control device 10a to control a plurality of antennas 11 1 to 11 5 used for communicating with a mobile station that moves along a predetermined path in a radio communication system that includes a plurality of linear cells, each of which is formed by the antennas and in each of which each of the antennas sets a directionality in a same direction as a path of the mobile station and transmits an identical signal at an identical frequency, and that has two frequencies recurrently allocated in such a manner that adjacent linear cells use different frequencies for transmission. The antenna control device adjusts, in each of the linear cells, power distribution to each of the antennas that form the linear cell so as to be gradually decreased with distance in a direction of antenna directionality of each of the antennas.
