Abstract
A reconfigurable antenna device suitable for a three-segment metal back cover is provided. The antenna device may include an antenna radiation body, a first matching module, a second matching module, a switch module and a feeding end. The antenna radiation body cab be parallel to and above a first metal body and a second metal body of the metal back cover. The antenna radiation body can be grounded after being connected to the first matching module. The antenna radiation body is further connected to the second matching module, and the second matching module is connected to the feeding end and a switch module, respectively. A multi-band reconfigurable antenna can be achieved by adjusting the position of the switch module.
