Guided near field communication for short range data communication |
摘要 |
A system is provided in which a set of modules each have a substrate on which is mounted a radio frequency (RF) transmitter and/or an RF receiver coupled to a near field communication (NFC) coupler located on the substrate. Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a field confiner located between the NFC coupler and the port region on the housing configured to guide electromagnetic energy emanated from the NFC coupler through the port region to a port region of an adjacent module. |

1. A system comprising a first module, in which the module includes:
a substrate on which is mounted a radio frequency (RF) transmitter coupled to a first near field communication (NFC) coupler located on the substrate; a housing that surrounds and encloses the substrate, the housing having a first port region on a surface of the housing; and a first field confiner located between the first NFC coupler and the first port region on the housing configured to propagate, near-field and/or evanescently couple electromagnetic energy emanated from the first NFC coupler through the first port region; in which the substrate has a conductive layer and a signal layer separated by an insulating layer; and in which the first NFC coupler includes a portion of the conductive layer in which an approximately circular slot has been removed leaving a circular conductive region and a first signal line on the signal layer that terminates over the circular region, passes over the circular slot, and couples to the transmitter. |
