Abstract:
Es wird eine iegsame Antennenanordnung, bestehend aus einem textilen Flächengebilde und einem darauf angeordneten mehradrigen Antennenleiter beschrieben. Der Antennenleiter (10) auf einem biegsamen, elektrisch nicht leitfähigen Träger (12) angeordnet, wobei der Träger aus einem Film, einer Folie oder einem textilen Flächengebilde besteht, und der Antennenleiter (10) aus mehreren parallel zueinander verlaufenden Leiterbahnen (14, 16, 18, 20) besteht, die elektrisch gegenseitig isoliert sind.
Abstract:
The present disclosure relates to a telecommunications jack including a housing having a port for receiving a plug. The jack also includes a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing, and a plurality of wire termination contacts for terminating wires to the jack. The jack further includes a circuit board that electrically connects the contact springs to the wire termination contacts. The circuit board includes a crosstalk compensation arrangement for reducing crosstalk at the jack. The circuit board also includes arrangements that reduce return loss at the jack.
Abstract:
L'invention se rapporte à un circuit imprimé flexible (10, 200) de forme longitudinale, comprenant au moins une piste conductrice (101, 201, 202, 203) s'étendant sur la longueur du circuit imprimé flexible, le circuit imprimé flexible comprenant au moins une zone de pliage (105, 205) conformée pour autoriser le passage dudit circuit imprimé flexible d'un état déplié à un état plié dans lequel la piste conductrice forme au moins une boucle d'antenne.
Abstract:
A printed circuit board (PCB) is disclosed. The PCB (200) includes a substrate (202) have a top surface (202a) and a bottom surface (202b). A first conductive layer (203) is disposed on the top surface of the substrate. The first conductive layer comprises a first signal net (203a) and a second signal net (203b). An outermost insulating layer (204) is disposed on the top surface of the substrate to cover the substrate and the first conductive layer. The outmost insulating layer comprises an opening (209) to expose a portion of the second signal net. And, a second conductive layer (207) is disposed on the outermost insulating layer and substantially covering at least a portion of the first signal net. The second conductive layer is filled into the opening to electrically connect to the second signal net which is able to provide one of a ground potential and a power potential. The thickness of outermost insulating layer (204) is less than 1 mm.
