Abstract: A method and near field communications (NFC) system for sensing at least one of an environmental condition or a composition of media in a proximity of the NFC system are provided. In the method and system, a first antenna irradiates an electromagnetic field during a sensor mode. A second antenna detects the electromagnetic field and outputs a voltage representative of the detected electromagnetic field. An NFC controller receives a signal representative of the voltage. The NFC controller determines at least one of the environmental condition or the composition of media based on an association stored in memory between the voltage and the at least one of the environmental condition or the composition of media.

Abstract: An embodiment electronic device includes a ground plane; and an antenna. The antenna includes a first trace having a first end and a second end, the second end of the first trace being electrically coupled to the ground plane. The antenna also includes a second trace distinct and physically separated from the first trace, the second trace having a first end and a second end, the second end of the second trace being electrically coupled to the ground plane, the first trace and the second trace forming discontinuous portions of the antenna.

Abstract: A near field communications (NFC) transponder includes a transmit circuit coupled to a transmit antenna and a receive circuit coupled to a receive antenna. The transmit/receive antennae are configured such that no signal is induced on the receive antenna by operation of the transmit antenna. Advantageously, this permits continued reception by the receive antenna while the transmit antenna is used for transmission using active load modulation.
