Abstract

An exemplary antenna module includes a metal unit, a ground unit, a feed unit, and a resonating unit. The metal unit is a metal housing or a metal sidewall of a wireless communication device. One end of the ground unit is connected to the metal unit and another end of the ground unit is grounded. One end of the feed unit is connected to the metal unit and another end of the feed unit is connected to a feed point of the wireless communication device. The resonating unit and the metal unit cooperatively generate a resonating, thereby receiving/sending wireless signals in corresponding frequency bands.
