Abstract
An antenna extender includes a body having a supporting structure configured to receive a smart card, a first antenna electrically connected to a second antenna, the first antenna configured to inductively couple with a near field communication (NFC) antenna on a host device, the second antenna configured to inductively couple with an NFC antenna on the smart card.
Claims22
An antenna extender, comprising:
- a body having a supporting structure configured to receive a smart card;
- a first antenna electrically connected to a second antenna, the first antenna configured to inductively couple with a near field communication (NFC) antenna on a host device, the second antenna configured to inductively couple with an NFC antenna on the smart card.
A method for improving power transfer between a smart card and a host device, comprising:
- aligning a first antenna on a first side of an antenna extender in proximity to a host NFC antenna on a host device;
- aligning a second antenna on a second side of the antenna extender in proximity to an antenna on a smart card;
- and
- maximizing power transfer from the host device to the smart card through the antenna extender.
