RFID strap capacitively coupled and method of making same

摘要

An electronic assembly with integrated circuit capacitively coupled to antenna. The electronic assembly includes a strap assembly and an antenna assembly. The antenna assembly includes a first substrate and antenna elements. The strap assembly includes a second substrate and an integrated circuit embedded within the second substrate and substantially flush with a surface of the second substrate. Interconnections are formed to the integrated circuit. The interconnections are formed on the surface of the second substrate. The antenna assembly and the strap assembly are affixed to one another with the surface of the second substrate facing the antenna elements. The antenna elements capacitively couples to the integrated circuit through the interconnections with no direct contact. A non-conductive layer is disposed between the antenna elements and the interconnections providing the capacitive coupling.
