COMMUNICATION DEVICE AND SEMICONDUCTOR CHIP

摘要

A device includes a first substrate that has a first antenna having a first loop and second loop that form loop shapes viewed in a planar projection; and a second substrate that has a second antenna having a third loop and fourth loop that form loop shapes viewed in the planar projection. The first substrate and the second substrate are disposed so that the first antenna and the second antenna face each other. At least when the first substrate and the second substrate operate, the first antenna and the second antenna are in a state that the first antenna and the second antenna are capable of being magnetically coupled.
