CA 2358125

A mobile communication base station determines the oncoming direction of a radio wave with a simple arrangement and transmits a narrow angle beam in this direction. Received signals from a pair of wide angle beam antennae having an equal configuration and a common orientation and which are located close to each other are fed to a direction finder receiver and a communication receiver. By utilizing the fact that the both received signals have a coincident amplitude, a phase difference between the received signals is detected. The oncoming direction of the received radio wave (or the direction of a mobile station) is determined on the basis of the phase difference. A beam switcher is controlled so as to connect a transmitter to a narrow angle beam antenna which is directed in the oncoming direction thus determined.
