PORTABLE COMMUNICATION DEVICE COMPRISING AN ANTENNA, WHEREIN A DELIBERATE MISMATCH IS INTRODUCED BETWEEN THE COMMUNICATION DEVICE AND THE ANTENNA WITHIN A FREQUENCY BAND

摘要

The present invention relates to a portable communication device (10) having an antenna (11). Within a frequency band of interest, there is a deliberate mismatch between the impedances of the antenna (11) and the communication device (10). In this way the transmission loss between the antenna (11) and the communication device (10) is equalized as function of the distance between a disturbing object and the antenna (11). In this way power can be saved and/or the performance can be improved in the portable communication device (10).
