An electromagnetic coupling module includes a feed circuit substrate having external coupling electrodes on both main surfaces thereof and a wireless IC chip. Radiation electrodes (22) and (32) are formed on a packaging body (30). The electromagnetic coupling module is disposed on a joint (9c) of the packaging body (30) so that the external coupling electrodes on both the main surfaces of the electromagnetic coupling module are coupled to the radiation electrodes (22) and (32), respectively. Thus, there is formed a wireless IC device that is resistant to shock or the like, easy to manufacture, and obtains stable characteristics and that allows easy reuse or replacement of an IC chip.

Es wird eine Messvorrichtung zur Erfassung der Kolbenposition in einem Fluidikzylinder (10) vorgeschlagen. Hierzu sind eine Mikrowellen-Koppelsonde (20) in einem Zylinderdeckel (11) des Fluidikzylinders (10) zur Einkopplung einer Hohlleiterwelle in den angrenzenden Zylinderraum (21) und zur Auskopplung und Erfassung der vom Kolben (13) reflektierten Hohlleiterwelle sowie eine Auswerteelektronik zur Auswertung der reflektierten Hohlleiterwelle vorgesehen. Die Koppelsonde (20) wird durch zwei sich in entgegengesetzte radiale Richtungen erstreckende Monopole (28, 29) gebildet, die jeweils in einem Dielektrikum (25, 26) angeordnet sind, wobei die beiden Dielektrika (25, 26) durch einen metallischen Steg (24) voneinander getrennt sind. Hierdurch können Zylinder beziehungsweise Zylinderdeckel realisiert werden, deren konzentrischer Mittelbereich fluidische Zuleitungen und sonstige Ausnehmungen enthalten kann und eine konzentrische Koppelsonde nicht erforderlich sind.

In accordance with one embodiment of the present disclosure, methods and systems for radiating elements are provided. In a method embodiment, a method of forming a radiating element (102) includes forming a pair of conductive surfaces (110a,110b) having first and second portions. The first portion is a dipole arm (115). The conductive surfaces are separated by a tapered notch (116) that has a width at a first end that is less than a width of a second end. For each conductive surface, the method also includes capacitively coupling the first portion of the conductive surface to the second portion of the conductive surface.
摘要:
A portable wireless device such as a folding portable telephone. Electric power is supplied by power supply wiring (7) placed between an upper printed board (4) and a lower circuit board (5). The upper printed board (4) and the lower printed board (5) form a radiation element. A portable wireless device body is made to function as a dipole antenna, and an upper/lower circuit connection section (6) for connecting the upper circuit board (4) and the lower circuit board (5) is composed of the power supply wiring (7) and signal wiring (10). The signal wiring (10) connects a circuit section of the upper printed board (4) and a circuit section of the lower printed board (5) and operates a receiver, a display (8), a microphone, an external interface, etc. The construction prevents damage to the signal wiring (10) caused by friction between the power supply wiring (7) and the signal wiring (10) occurring when the folding portable telephone is opened and closed, and realizes downsizing of the folding wireless device.
