Abstract
The present invention relates to a portable communication device and a method of controlling the matching of an antenna in a portable communication device. The device may include an antenna; a radio circuit to send a radio frequency signal to the antenna via a signal path; a matching network including a number of network components and configured to be in the signal path; a detector configured to detect an electromagnetic field from the antenna; and a control unit configured to control matching of the antenna by influencing at least one of the first matching network or the antenna based on the detected electromagnetic field.
