A radio frequency identification (RIFD) inlay includes an electrical connection between a chip and an antenna. The electrical connection includes conductive interposer leads and a capacitive coupling. The capacitive connection may involve putting the antenna and the interposer leads into close proximity, with dielectric pads therebetween, to allow capacitive coupling between the antenna and the interposer leads. the capacitive coupling includes at least one feature to reduce effects of at least one of 1) misalignment of the interposer leads and the antenna, and 2) variations in thickness of the dielectric material.

Une incrustation d'identification par radiofréquence (RFID) comprend une connexion électrique entre une puce et une antenne. Cette connexion électrique comprend des fils d'interposition conducteurs et un couplage capacitif. La connexion capacitive peut consister à placer l'antenne et les fils d'interposition à proximité étroite, avec des blocs diélectriques entre ceux-ci, de façon à permettre un couplage capacitif entre l'antenne et les fils d'interposition. Ce couplage capacitif comprend au moins un élément destiné à réduire les effets de (1) défaut d'alignement des fils d'interposition et de l'antenne et (2) de variations d'épaisseur du matériau diélectrique.
