Abstract
The object of the present invention to provide a directional beam communication system whereby the beam width of a directional beam to be transmitted is reduced by sharing an array antenna among a plurality of adjacent sectors so as to increase the interference suppression effect. The directional beam communication system is configured to communicate with a mobile station MS located in a service area formed by a plurality of sectors S1 and S2 using a directional beam which is transmitted by an array antenna A including a plurality of antenna elements a. The array antenna A for transmitting the directional beam is shared among at least two adjacent sectors S1 and S2.
