Center Offset Fed Multiband Monopole Antenna and Portable Radio Communication Device Comprising Such An Antenna

摘要

Exemplary embodiments are disclosed of antenna devices for portable radio communication devices. In an exemplary embodiment, an antenna device comprises a monopole radiating element to be positioned along one end of a portable radio communication device, for operation of a plurality of complementary frequency bands including the FM frequency band. A feed offset positioned on the monopole radiating element divides the monopole radiating element in a first part and a second part to provide at least one complementary frequency band additional to the FM frequency band. The FM frequency band and the at least one additional complementary frequency band are fed through the feed.
