Abstract
A multi-band antenna (1) for an electronic device comprises an insulative substrate (30), a feeder cable (40) and a conductive element disposed on the substrate including a radiating portion (21), a first connecting portion (22), a second connecting portion (23) and a ground portion (10). The radiating portion includes a plurality of radiating segments (211-218). The first and second connecting portions connect the ground portion with the radiating portion. A part of the radiating portion, the second connecting portion, the ground portion and the feeder cable form a planar loop antenna. The radiating portion, the first connecting portion, the ground portion and the feeder cable form a planar inverted-F antenna.
