Radio-frequency system

摘要

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.

主权项

1. A radio-frequency (RF) system for a wireless communication device, wherein the wireless communication device comprises a first board body and a second board body, and is capable of switching operations to a pad mode, in which an angle between the first broad body and the second broad body is less than a predefined value, or at least a non-pad mode, in which the angle is greater than the predefined value, the RF system comprising:
at least an antenna, disposed in the first board body and substantially extending along a first plane of the first board body, each of the antennas comprising a radiating element and a grounding element adjacent to the radiating element; and at least a metal wall, electrically connected to a system ground of the wireless communication device, disposed in locations of the second board body related to locations of the at least an antenna disposed in the first board body, and substantially extending along a second plane of the second board body; wherein 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 corresponding to the first plane; wherein when the wireless communication device operates in the pad mode, a projection result of each of the metal walls corresponding to the first plane is substantially adjacent to the radiating element of one of the at least an antenna.
