CENTER OFFSET FED MULTIBAND MONOPOLE ANTENNA AND PORTABLE RADIO COMMUNICATION DEVICE COMPRISING SUCH AN ANTENA

摘要

The present invention relates to an antenna device for a portable radio communication device (2), wherein the antenna device comprises a monopole radiating element (3) to be positioned along one end of the portable radio communication device, for operation of a plurality of complementary frequency bands including the FM frequency band. The antenna device further comprises a feed (4) offset positioned on the monopole radiating element dividing the monopole radiating element in a first part (5) and a second part (6) to provide at least one complementary frequency band additional to the FM frequency band, which FM frequency band and the at least two additional complementary frequency bands are fed through the feed.
