Abstract

This communication apparatus makes it possible to have a non-contact charging module and a sheet antenna coexist, even in the case where there the non-contact charging module and the sheet antenna in the communication apparatus. The apparatus is provided with: a housing; a secondary-side non-contact charging module, which is housed in the housing, receives power by means of electromagnetic induction, and has a first coil having a conducting wire wound thereon, and a first magnetic sheet facing the first coil; and an NFC antenna, which is housed in the housing, and has a second coil having a conducting wire wound thereon, and a second magnetic sheet facing the second coil. The secondary-side non-contact charging module and the NFC antenna are not laminated to each other.

Claims

1. A communication apparatus comprising:

a housing;

a non-contact charging module housed in the housing and configured to receive electric power through electromagnetic induction, the non-contact charging module including a first coil comprised of a wound electrical line and a first magnetic sheet facing the first coil; and

a sheet antenna housed in the housing and including a second coil comprised of a wound electrical line and a second magnetic sheet facing the second coil, wherein

the non-contact charging module and the sheet antenna are not stacked.
