Abstract
An antenna device for transmitting and receiving electromagnetic waves, wherein the antenna device includes a transmitter section and a receiver section. The receiver section includes a receiving antenna structure selectively switchable between a plurality of configuration states. The antenna structure may be switched by a switching device, which is controlled by a control device. The selective switching is effected based upon a first measure representing a reflection coefficient measured at the transmitter section. A method for transmitting and receiving electromagnetic waves includes receiving a measure representing a reflection coefficient and controlling a switching device to selectively switch an antenna structure between a plurality of antenna configuration states in response to the measure representing the reflection coefficient.
