Abstract

The present invention provides a planar multiband antenna having a ground area, a first radiation electrode, a second radiation electrode, a third radiation electrode and a feeder. The feeder is implemented to feed the first radiation electrode. The first radiation electrode is arranged at least partly between the ground area and the second radiation electrode and does not protrude from an external periphery of the third radiation electrode. The third radiation electrode is arranged such that it completely surrounds an external periphery of the second radiation electrode, wherein there is a gap between the second radiation electrode and the third radiation electrode.
