RF radiation redirection away from portable communication device user

摘要

A case for a wireless device includes a number of RF coupling elements mounted in the case and configured such that RF radiation is coupled from an internal antenna of the wireless device out of the device to a first RF coupling element, and from the first RF coupling element to a RF redirector coupling element that redirects the RF radiation in a direction outward from said wireless device that is opposite to a user side of the wireless device. A corrugated metallic shield is optionally provided on an opposite side of the case, facing a user of the device.

主权项

1. An apparatus, comprising:
an external case configured to be coupled to a wireless device having a case separate from the external case, the external case having a plurality of antenna elements disposed within an interior of the external case, a first antenna element from the plurality of antenna elements configured to be operatively coupled to an internal antenna of the wireless device to receive radiation from the wireless device when the external case is coupled to the wireless device and when the wireless device is operational, a second antenna element from the plurality of antenna elements configured to redirect the radiation from the first antenna element to a third antenna element from the plurality of antenna elements when the external case is coupled to the wireless device and when the wireless device is operational, the third antenna element configured to send the radiation from the second antenna element away from a user of the wireless device when the external case is coupled to the wireless device and when the wireless device is operational.
