1. An adaptive antenna unit which is adapted to a mobile terminal for making mobile communication and adaptively forms an antenna directivity in a direction of a base station which exchanges signals with the mobile terminal, comprising:

  • an azimuth sensor to detect at least one of rotation, inclination and present position of the mobile terminal;

    a transmitter-receiver section to control the antenna directivity in a direction in which a reception characteristic improves based on reception signals received from a plurality of antenna elements forming the antenna directivity; and

    means for correcting the antenna directivity in the direction of the base station, based on the at least one of rotation, inclination and present position of the mobile terminal detected by the azimuth sensor.
