METHOD FOR AUTOMATIC ADJUSTMENT OF A TUNABLE PASSIVE ANTENNA AND A TUNING UNIT, AND APPARATUS FOR RADIO COMMUNICATION USING THIS METHOD

摘要

The invention relates to a method for automatically adjusting one or more tunable passive antennas and a single-input-port and single-output-port tuning unit. The invention also relates to an apparatus for radio communication using this method, for instance a radio transceiver. An apparatus for radio communication of the invention comprises: a tunable passive antenna (1); a feeder (2); a single-input-port and single-output-port tuning unit (4); a sensing unit (3); a transmission and signal processing unit (8) which applies an excitation to the input port, which delivers one or more "antenna adjustment instructions", and which delivers one or more "tuning unit adjustment instructions"; and a control unit (6) which delivers one or more "antenna control signals" to the tunable passive antenna, and one or more "tuning control signals" to the single-input-port and single-output-port tuning unit.
