Abstract
A booster antenna (BA) for a smart card comprises a card antenna (CA) component extending around a periphery of a card body (CB), a coupler coil (CC) component at a location for an antenna module (AM), and an extension antenna (EA) contributing to the inductance of the booster antenna (BA). A method of wire embedding is also disclosed, by controlling a force and ultrasonic power applied by an embedding tool at different positions on the card body (CB).
Claims12
A booster antenna (BA) comprising at least a card antenna (CA) component extending around a periphery of a card body (CB) and an extension antenna (EA) component, characterized by:
- the extension antenna (EA) component has a sense opposite to that from the card antenna (CA) component.
Booster antenna (BA) comprising the following components:
- a card antenna (CA) component;
- a coupler coil (CC) component;
- and
- an extension antenna (EA) component;
- characterized in that:
- at least one of the components has a sense which is opposite one or more of the other components.
Booster antenna (BA) comprising:
- a card antenna (CA) component;
- a coupler coil (CC) component;
- and
- at least one capacitive stub connected with at least one of the coupler coil (CC) and card antenna (CA) components.
