ABSTRACT:
A multi-band antenna includes a first pole (2) and a second pole (3) connecting with the first pole. The first and second poles are both made of metal sheets. The first pole is rectangular in shape. The second pole includes a first section (31), a second section (32) and a third section (33). The second and third sections connect to the first section. The first, second and third sections integrally form a fork-shaped structure and each section has a different length. The first, second and third sections each radiate at a different frequency. A feeder device (5) includes a coaxial cable which electrically connects with the first pole and the second pole for feeding the antenna.
