Abstract: A radio-frequency system for a wireless communication device is disclosed. The wireless communication device includes a first board body and a second board body, capable of operating in a pad mode. The radio-frequency system includes at least one antenna disposed in the first board body and extending along a first plane, and at least one metal wall electrically connected to a system ground, disposed on the second board body related to locations of the at least one antenna disposed in the first board body, extending along a second plane. When the wireless communication device operates in the pad mode, the second plane is substantially perpendicular to the first plane, such that each of the metal walls has a height in comparison to the first plane, and a projecting result of each of the metal walls corresponding to the first plane is adjacent to a radiating element of an antenna.
