Abstract: An antenna device is formed by a first electrically conductive spiral having a first end connected to a first node and a second end connected to a second node, and a second electrically conductive spiral having a first end connected to the second node and a second end connected to a third node. The first and second nodes are configured for connection to an NFC driver circuit, with the first electrically conductive spiral forming an antenna for near-field communication. The first and third nodes are configured for connection to a wireless power charging driver circuit, with the first electrically conductive spiral and second electrically conductive spiral forming an antenna for wireless power charging.

Abstract: An antenna device for use with a wireless power charging operation and a near-field communication (NFC) operation is formed sets of electrically conductive loops. The sets include a first set of loops configured to form a NFC antenna and a second set of loops. The first and second sets of loops together are configured to form a wireless power charging antenna.
