Smartcard with coupling frame antenna
First Claim
1. Smartcard comprising:
- a card body (CB), wherein a given area of the card body is designated for receiving a transponder chip module (TCM) having a module antenna (MA);
characterized by;
a coupling frame antenna (CFA) comprising a conductive track routed around a perimeter of the card body, and further routed toward the interior of the card body to the area designated for receiving the transponder chip module, resulting in two portions of the coupling frame antenna (CFA) being closely adjacent one another with a gap (S, 203, 303) therebetween, the gap extending from a peripheral edge of the card body to the area of the card body designated for receiving the transponder chip module (TCM);
wherein;
the coupling frame antenna (CFA) comprises a single-turn, closed-loop circuit.

Abstract
Smartcard (SC) having a card body (CB) and a conductive coupling frame antenna (CFA) extending as a closed loop circuit around a periphery of the card body, and also extending inwardly so that two portions of the coupling frame antenna are closely adjacent each other, with a gap therebetween. The gap may extend from a periphery of the card body to a position corresponding with a module antenna (MA) of a transponder chip module (TCM) disposed in the card body, and may function like a slit (S) in a coupling frame (CF). A portion of the coupling frame antenna may be arranged to surround the ISO position of the transponder chip module in the card body. A coupling frame antenna (CFA) may be incorporated onto a module tape (MT) for a transponder chip module (TCM).
