Abstract
A multi-band antenna (1) includes a grounding portion (10), a first radiating arm (21), a second radiating arm (22), a connection portion (23) and a feed line (40) being soldered to the connection portion. The connection portion includes an end connecting with the grounding portion and an opposite end connecting with the first and the second radiating arms. The feed line is soldered to a selected section of the connection portion. The selected section is arranged between two ends of the connection portion. By changing the solder point of the feed line on the connection portion, the characteristics of the multi-band antenna can be conveniently and precisely adjusted.
