Abstract
A conductive coupling frame (CF) having two ends, forming an open loop having two ends or a discontinuous metal layer disposed surrounding and closely adjacent a transponder chip module (TCM,), and substantially coplanar with an antenna structure (AS, CES, LES) in the transponder chip module (TCM). A metal card body (MCB, CB) or a transaction card with a discontinuous metal layer having a slit (S) or a non-conductive strip (NCS,) extending from a module opening (MO) to a periphery of the card body to function as a coupling frame (CF). The coupling frame (CF) may be thick enough to be non-transparent to RF at frequencies of interest. A switch (SW) may be provided to connect ends of the coupling frame (CF) across the slit (S,). A reinforcing structure (RS) may be provided to stabilize the coupling frame (CF) and card body (CB). The transponder chip module (TCM) may comprise an antenna structure which may be a laser-etched antenna structure (LES) or a chemical-etched antenna structure (CES), and may comprise and a non-perforated contact pad (CP) arrangement. A coupling frame (CF) may be incorporated onto the module tape (MT, CCT) for a transponder chip module (TCM).
