Abstract

The present invention comprises an antenna device (1) for transmitting and receiving radio waves, connectable to a radio communication device, and comprising transmitter (2) and receiver (3) sections. The receiver section includes a receiving antenna structure (13, 35, 61, 82-85, 87, 89, 91, 92) switchable between a plurality of antenna configuration states, each of which is distinguished by a set of radiation related parameters, such as resonance frequency, impedance, radiation pattern, polarization and bandwidth, and a switching device (14, 36, 81) for selectively switching said antenna structure between said plurality of antenna configuration states. The antenna device comprises further a receiving means for receiving a first measure representing the reflection coefficient in the transmitter section, and a control device (22) for controlling the switching device of said receiver section, and thus the selective switching of the antenna structure between said plurality of antenna configuration states, in dependence on said first received measure representing the reflection coefficient.
