Abstract
A single-antenna solution is provided for near-field and far-field communication in wireless devices. In an embodiment, a first transceiver block generates a first transmit signal to be transmitted using radiative techniques. A second transceiver block generates a second transmit signal to be transmitted using inductive coupling. The first and second transceiver blocks are coupled to a same antenna for transmitting the first transmit signal using radiative coupling, and the second transmit signal using inductive coupling. The first transceiver block and the second transceiver block operate according to time division multiplexing, and in an embodiment corresponding to an FM transceiver and an NFC transceiver.
