Near field communication on a seamless metal band and metal backed device
First Claim
1. A device comprising:
- a housing including a one-piece metal back coupled to an external component casing, the housing utilized to enclose components of the device, the external component casing configured to include a keep-out area that is covered by a different material from the one-piece metal back to reduce electrical interference for components within the keep out area;
a seamless metal band that extends from the one piece metal back into the keep-out area, the seamless metal band and the one-piece metal back being a seamless structure manufactured as a single metal piece, without any breaks, and are a single conducting unit, the seamless metal band being positioned in the keep-out area of the component casing, the seamless metal band being an antenna coil adapted to function as a dual-band antenna;
a second coil, separate from the antenna coil, the second coil operable as at least one of a near field communication coil and a wireless power transmission coil;
at least one diplexing component coupled to both the second coil and to the antenna coil of the dual-band antenna; and
a transceiver circuit communicatively coupled to the dual-band antenna; and
wherein the second coil is adapted to provide a secondary device function contemporaneously with a wireless communication function of the dual band antenna.

Abstract
A method and a mobile device that provides near field communication and wireless powering capabilities by coupling a one-piece metal back and a metal band to a device housing to form a device. The device is configured to provide at least one antenna keep-out area. The metal band is adapted to be a dual-band antenna that is coupled to a coil. The coil, operable as one of a near field communication coil and a wireless power transmission coil, forms an overlapping trace with the dual-band antenna along at least one physical area. The coil and the dual-band antenna are positioned in the antenna keepout area and around the perimeter of the device. The method further includes forming at least two turns in the coil. At least one diplexing component is coupled both to the coil and to the dual-band antenna.
