RADIO COMMUNICATION USING TUNABLE ANTENNAS AND AN ANTENNA TUNING APPARATUS

摘要

Radio communication using tunable antennas and an antenna tuning apparatus The invention relates to a method for radio communication using one or more tunable antennas and an antenna tuning apparatus, and to an apparatus for radio communication using one or more tunable antennas and an antenna tuning apparatus. An apparatus for radio communication of the invention comprises: 4 antennas (11) (12) (13) (14), the 4 antennas forming an antenna array (1), each of the antennas being a tunable passive antenna; a radio device (5); an antenna tuning apparatus (3) having 4 antenna ports (311) (321) (331) (341), each of the antenna ports being coupled to one of the antennas through a feeder (21) (22) (23) (24), the antenna tuning apparatus having 4 radio ports (312) (322) (332) (342), each of the radio ports being coupled to the radio device (5) through an interconnection (41) (42) (43) (44); and a tuning control unit (7), the tuning control unit receiving a tuning instruction generated automatically within the apparatus for radio communication, the tuning control unit delivering a plurality of tuning control signals to the antenna tuning apparatus and to the tunable passive antennas.
