Abstract

A capacitive coupling enhanced (CCE) transponder chip module (TCM) comprises an RFID chip (CM, IC), optionally contact pads (CP), a module antenna (MA), and a coupling frame (CF), all on a common substrate or module tape (MT). The coupling frame (CF,A) may be in the form of a ring, having an inner edge (IE), an outer edge IE,) and a central opening (OP), disposed closely adjacent to and surrounding the module antenna (MA). A slit (S) may extend from the inner edge (IE) to the outer edge (OE) of the coupling frame (CF) so that the coupling frame (CF) is 'open loop'. An RFID device may comprise a transponder chip module (TCM) having a module antenna (MA), a device substrate (DS), and an antenna structure (AS) disposed on the device substrate (DS) and connected with the module antenna (MA). A portion of a conductive layer (CL,) remaining after etching a module antenna (MA) may be segmented to have several smaller isolated conductive structures.
