Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.

Abstract: A mobile terminal and a mobile terminal antenna production method. The mobile terminal uses an insulation film layer on an insulation rear housing as a carrier of a radiating element of an antenna, and the radiating element is located within the entire mobile terminal. A feed and an electric-conductor are disposed on a circuit board, and the electric-conductor is electrically connected to the feed. There is a gap between the radiating element and the electric-conductor, and the electric-conductor indirectly couples the radiating element in a capacitively coupled manner.

Abstract: A mobile terminal and a mobile terminal antenna production method. The mobile terminal uses an insulation film layer on an insulation rear housing as a carrier of a radiating element of an antenna, and the radiating element is located within the entire mobile terminal, thereby effectively increasing a height of the radiating element of the antenna relative to a circuit board with the antenna not affecting an appearance of the mobile terminal. Compared with a conventional support solution, this manner can increase a height of about 0.2 mm to 0.6 mm. This reduces an impact caused by a metal component on the circuit board on antenna radiation, and further increases a bandwidth and efficiency of the antenna so that the antenna can cover a frequency band used in a handheld communications system.

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.

Abstract: This application discloses a slot antenna and a terminal. The slot antenna includes a ground plane, an open slot disposed on the ground plane, a slot feeder, and a resonant circuit. The resonant circuit effectively excites a current on a surface of the ground plane, so that the ground plane becomes a primary radiator, and the antenna is a secondary radiator. Therefore, a volume of the antenna can be reduced without affecting radiation efficiency of the antenna.

Abstract: An ultra-wide band (UWB) antenna and a plug-and-play (PnP) device using the same are provided. A dielectric substrate of the PnP device has a ground plane. The UWB antenna includes a radiating metal plate and a feeding portion. The radiating metal plate is in a non-ground region of the dielectric substrate and has at least a slit cut. An opening of the slit cut is at the edge of the radiating metal plate facing the ground plane. The feeding portion is also at the edge of the radiating metal plate facing the ground plate for feeding a signal to the antenna.

Abstract: A broadband dipole antenna includes a dielectric substrate, a first radiating portion, a second radiating portion, a substantially U-shaped or V-shaped feed gap, and two feed points. The feed gap is located in-between the first radiating portion and the second radiating portion. The two feed points are located in the first radiating portion and the second radiating portion, respectively, and separated by the feed gap.

Abstract: A broadband antenna is capable of generating an upper resonant mode (at about 700 MHz) from a first radiating arm and a lower resonant mode (at about 500 MHz) from a second radiating arm. The first and second radiating arms are bent at least one time. An open end of the second radiating arm is extended toward an open end of the first radiating arm with a predefined distance there between. The predefined distance can be adjusted to improve the impedance matching of lower resonant mode, which can be further combined with the upper resonant mode to achieve a broad bandwidth covering the complete spectrum of digital TV channels (470-862 MHz).
