Abstract
This document discloses one or more systems, apparatuses, methods, etc. for integrating coil antennas in a carbon fiber chassis portable device. More particularly, the carbon fiber chassis portable device containing unidirectional weave carbon fibers in its chassis—to support near field communications (NFC) related functions—is described.
Claims20
A device comprising:
- one or more processors;
- a memory configured to the processors;
- a near field communications (NFC) antenna configured to the processors, the NFC antenna integrated within a carbon fiber reinforced polymer (CFRP) chassis of the portable device, the CFRP chassis includes bundles of carbon fiber strands that are positioned to form a unidirectional weave.
A near field communications (NFC) antenna comprising:
- a continuous loop of coil antenna that is integrated within a carbon fiber reinforced polymer (CFRP) chassis of a portable device, the CFRP chassis includes carbon fiber strands in a single direction to cover the coil antenna;
- and
- an NFC module to provide tuning to the coil antenna.
A method of integrating a near field communications (NFC) antenna to a carbon fiber reinforced polymer (CFRP) chassis portable device, the method comprising:
- weaving bundles of carbon fiber in a unidirectional and parallel configuration, wherein the bundles of carbon fiber are interlaced with non-conductive materials;
- positioning the weaved bundles of carbon fiber to a direction of a loop of the NFC antenna;
- radiating electromagnetic fields by the NFC antenna;
- inducing a current to the weaved bundles of carbon fiber by the radiated electromagnetic fields;
- and
- providing high impedance to the induced current.
