Abstract: A terminal device includes a housing and a metal line that is disposed on an outer surface of the housing or is embedded in the housing, and the metal line is configured to receive or send an electromagnetic wave signal. The metal line acts as an antenna of the terminal device.

Abstract: Embodiments of this application provide a middle frame, a rear cover, and fabrication methods thereof, and an electronic device. The electronic device may include a mobile or fixed terminal with a frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS terminal, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Ceramics and fiber reinforced composite are used to form frames of a rear cover and a middle frame, to reduce thicknesses of a ceramic outer housing and a ceramic outer frame, thereby reducing a weight of the electronic device.

Abstract: This application provides a terminal device which includes a housing and a metal line. The metal line is disposed on an outer surface of the housing or embedded in the housing, and the metal line is configured to receive or send an electromagnetic wave signal. In the terminal device provided in this application, the metal line (an antenna) of the terminal device is disposed on the outer surface of the housing of the terminal device or embedded in the housing. This can increase a distance from the metal line to a circuit board of the terminal device, thereby reducing interference of a metal component on the circuit board to radiation of the metal line (radiation of the antenna) and improving operating bandwidth and efficiency of the antenna. This improves operating efficiency of the antenna of the terminal device, thereby improving signal receiving and signal sending quality of the terminal device.
