摘要:
A mobile communication device including a system ground plane, an antenna, a signal distributor, a transceiver and a sensing controller is provided. The antenna converts an electromagnetic wave to a radio-frequency signal. Besides, the antenna and the system ground plane form a sensing capacitor to detect an object and generate a detecting signal accordingly. The signal distributor is electrically connected to the antenna through a first connection terminal and a second connection terminal and guides the radio-frequency signal and the detecting signal from the antenna to a third connection terminal and a fourth connection terminal. The transceiver is electrically connected to the third connection terminal and processes the radio-frequency signal. The sensing controller is electrically connected to the fourth connection terminal and determines whether the object exists around the antenna according to the sensing signal.

An antenna module includes a substrate, a main radiation structure, a strip-shaped radiation structure, a grounding structure, a shorting structure, a parasitic radiation structure and a metal radiation member. An acute angle is included between a first edge of the main radiation structure and a longitudinal edge of the substrate. The main radiation structure has a signal feeding portion and a connecting portion. The strip-shaped radiation structure is extended from a second edge of the main radiation structure. The shorting structure is U-shaped. A first end of the shorting structure is connected to the signal feeding portion and a second end of the shorting structure is connected to the grounding structure. The parasitic radiation structure is extended from the grounding structure and parallel to the first edge. A constant distance is between the parasitic radiation structure and the first edge. The metal radiation member is connected to the connecting portion.

A method for dicing a semiconductor wafer includes the steps of: forming grooves in an integrated circuit layer of the semiconductor wafer; forming a photoresist layer on the integrated circuit layer; forming V-shaped first notches, each of which is further indented from the integrated circuit layer; thinning the substrate; attaching a blue tape to the integrated circuit layer; forming V-shaped second notches, each of which is indented from the thinned substrate and each of which is registered with a respective one of the first notches such that the first and second notches cooperatively define imaginary breaking lines, respectively; and pressing the blue tape at positions that are aligned with the imaginary breaking lines, respectively.

A periodically structured substrate includes a slab and a periodic structure formed on the slab and including a plurality of spaced apart first surrounding elements and a plurality of spaced apart central elements. The first surrounding elements are periodically arranged in such a manner to form repeating polygonal patterns. Each of the central elements is disposed at a center of a respective one of the polygonal patterns. The periodic structure further includes a spacer medium that fills a space among the central element and the first surrounding elements of each of the polygonal patterns and that has a refractive index different from those of the central element and the first surrounding elements.
