A multi-band antenna, comprising:

• a first antenna having a first radiating portion;
• a second antenna having a second radiating portion;
• a third antenna having a third radiating portion;
• and
• a feeder;
• wherein said first, second and third antennas have a common ground portion and a collective feeder, and said first, second and third radiating portions are connected with each other, the second and the third radiating portions define an inverted-L shaped slit therebetween.

A multi-band antenna comprising:

• a common ground portion;
• a first radiation section extending from an upward edge of the ground portion;
• essentially parallel spaced second and third radiation section joined at a distal end of the first radiation section, said radiation section being closer to the ground portion than the third radiation section;
• and
• a feeder cable including an outer connected to the ground portion and an inner conductor connected to the second radiation section.
