Abstract (en)
[origin: WO2013110625A1] A dual-interface smart card having a booster antenna (BA) with coupler coil (CC) in its card body (CB), and a metallized face plate (202, 302) having a window opening (220, 320) for the antenna module (AM). Performance may be improved by one or more of making the window opening substantially larger than the antenna module, providing perforations through the face plate, disposing ferrite material between the face plate and the booster antenna. Additionally, by one or more of modifying contact pads (CP) on the antenna module (AM), disposing a compensating loop (CL) under the booster antenna, offsetting the antenna module with respect to the coupler coil, arranging the booster antenna as a quasi-dipole, providing the module antenna (MA) with capacitive stubs, and disposing a ferrite element (FE) in the antenna module between the module antenna and the contact pads.
