Abstract: The present disclosure provides a method for fabricating an image sensor. The method includes the following operations. A cavity is formed at a first surface of a substrate. A germanium layer is formed in the cavity. A first heavily doped region is formed in the germanium layer by an implantation operation. A second heavily doped region is formed at a position proximal to a top surface of the germanium layer, wherein the second heavily doped region is laterally surrounded by the first heavily doped region from a top view perspective. An interconnect structure is formed over the germanium layer.

Abstract: An antenna structure includes a first antenna, a second antenna, a third antenna, and a first grounding portion. The first antenna and the second antenna operate at a first frequency. The first antenna is disposed side by side with the second antenna, and the first antenna and the second antenna are orthogonally polarized. The third antenna operates at a second frequency, and the second frequency is lower than the first frequency. The first grounding portion includes a first side edge and a second side edge opposite to each other. The first antenna and the second antenna are connected to the first side edge and the third antenna is connected to the second side edge. An electronic device includes the said antenna structure.

Abstract: A dual band antenna module including a first radiator, a second radiator, a first filter and a second filter is provided. The first radiator resonates to generate a first frequency band and includes a first feeding end and a first ground end. The second radiator resonates to generate a second frequency band and includes a second feeding end and a second ground end. The first filter is extended from the first feeding end in a direction away from the first radiator and used for filtering the second frequency band. The second filter is extended from the second feeding end in a direction away from the second radiator and used for filtering the first frequency band.

Abstract: A dual band antenna apparatus including a heat sink and a dual band antenna is provided. The heat sink is disposed on the dual band antenna. The dual band antenna includes a first radiator and a second radiator. The first radiator and the heat sink are oppositely disposed. The first radiator has a first open terminal, a first ground terminal and a feeding point. The first radiator receives a feeding signal through the feeding point to generate a first resonance mode, and thus the dual band antenna is capable of receiving or sending and both a first band signal. The second radiator is connected to the heat sink and has a second open terminal and a second ground terminal. The second open terminal of the second radiator is coupled with the first radiator and excited to generate a second resonance mode, thus the dual band antenna is capable of receiving or sending and both a second band signal.

Abstract: A process for manufacturing wheel hub comprises an iron tube being swaged in wave form that can be cut to form a plurality of axle tubes; a plurality of bearing receiving bowls and a plurality of bowl holders. Each axle tube has a hub flange by stamping. Each hub flange has at its face plate a plurality of spoke holes and therein a bowl receiving recess. For the front wheel hub each bearing receiving bowl has at its bottom center an axial hole corresponding to the axial hole of the axle tube. In alignment with the axial hole of the bearing receiving bowl and the axial hole of the axle tube, the bearing receiving bowls are respectively provided for permitting to insert into the bowl receiving recesses and defining as a front wheel hub. For the rear wheel hub, the bowl holders have an inner surface, attaching to the outer portion of each bearing receiving bowl by brazing, being defined as a front portion.
