Abstract
Official abstract text for this publication.
A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. An operator may touch, or be sufficiently proximate to, an antenna module of the NFC device to operate and/or control the NFC device. The antenna module includes antenna components that are characterized by a corresponding characteristic impedance. The touch, or sufficient proximity, of the operator changes the corresponding characteristic impedance of antenna components. The NFC device may determine a location of the touch, or proximity, of the operator based upon this change. The NFC device may interpret the location of the touch, or proximity, of the operator as information from the operator to operate and/or control the NFC device.
First claim
Opening claim text (preview).
What is claimed is: 1. A communications device, comprising: an antenna module, having a plurality of antenna components, configured to receive a communications signal, the plurality of antenna components comprising: a plurality of geometric shapes coupled in series, each of the plurality of geometric shapes being characterized by a corresponding characteristic impedance from among a plurality of characteristic impedances, the corresponding characteristic impedance being configure…
