MULTIBAND ANTENNA

摘要

A multiband antenna includes a radiating portion and a ground portion. The radiating portion includes a first radiating section, a second radiating section and a coupling section. The coupling section is coupled between the first radiating section and the second radiating section. The ground portion includes a first ground section, a second ground section and a third ground section. The second ground section and the third ground section both coupled to a first side of the first ground section. The coupling section and the second radiating section are accommodated in a surrounded area defined inside the first ground section, the second ground section and the third ground section, and the first radiating section extend outside the surrounded area.
