Abstract
A multi-band antenna structure includes a ground plane, a first radiation metal arm, a first shorted parasitic arm and a second shorted parasitic arm. The first radiation metal arm is connected to a main transmitting antenna and has a first feed point for connecting a first feed line. The first shorted parasitic arm extends to the outside from the ground plane. The first shorted parasitic arm is between the first radiation metal arm and the ground plane for resonantly coupling the first radiation metal arm at a first band. The second shorted parasitic arm also extends to the outside from the ground plane. The second shorted parasitic arm is between the first radiation metal arm and the first shorted parasitic arm for resonantly coupling the first radiation metal arm at a second band.
