Abstract
A triple-band embedded antenna includes an antenna base and a metal connecting board. A left groove, a right groove and a square opening are formed in the antenna base. A left branch is separated from the antenna base by the left groove, the left branch arranged in the outside of the left groove, a signal feed point formed in the left branch. A right branch is separated from the antenna base by the right groove, the right branch arranged in the outside of the right groove, a ground point formed in the right branch. The antenna base is for receiving or radiating the low frequency band signal. The left groove is for receiving or radiating the high frequency band signal. While the right groove coupled with the left groove, the left groove can receive or radiate another high frequency band signal, which is the third frequency band signal.
