US Patent:

8214003, Jul 3, 2012

Filed:

Mar 15, 2010

Appl. No.:

12/724290

Inventors:

Alfred Y. Wong - Los Angeles CA, US
Robert Moreno - Acton CA, US
Karl Richard Shields - North Hills CA, US
Rong Wang - Sherman Oaks CA, US

Assignee:

Pong Research Corporation - Leesburg VA

International Classification:

H04W 88/02

US Classification:

4555755, 4555751, 4555757, 455 903

Abstract:

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.

Abstract:

An antenna or set of antennae for a wireless device is provided by embedding the antennae into the battery case or generally the surface area of a wireless phone. The antenna connections are through the battery's connections to the wireless device. The antenna can be located at the back surface of the battery or the rear surface of a wireless phone, facing away from the user. An RF shielding device can be embedded into the battery and configured in relation to the antenna such that the RF field intensity and the consequent specific absorption rate for the user is lowered while the outgoing signals of the wireless device remain fully adequate for the function of the wireless device. This feature is preserved for a multi-band operation because a digital phase shifter is used between two radiating antennae. An external case is used as a complement to the wireless phone.

Abstract:

An advanced antenna or set of antennae for a wireless device is provided by embedding the antennae into the battery case or generally the largest surface area of a wireless phone. The antenna connections are made through the battery's connections to the wireless device. The antenna design can be compact and located in any area of the battery. The antenna design can be thin and flat, located at the back surface of the battery or the large rear surface of a wireless phone, facing away from the user. An RF shielding device can be embedded into the battery and configured in relation to the antenna such that the RF field intensity and the consequent specific absorption rate for the user is lowered while the outgoing signals of the wireless device remain fully adequate for the function of the wireless device. This feature is preserved for a multi-band operation because a digital phase shifter is used between two radiating antennae. An external case is used as a complement to the wireless phone to provide additional antennae, power and capability.

International Classification:

H01Q 1/24

US Classification:

343702

Abstract:

A case for a wireless tablet computer device includes a number of RF resonant loop elements and elongated RF director coupling strip 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 the RF resonant and coupling elements. The case incorporates a cut-out section in a location leaving exposed a strip that covers an area proximate the internal antenna. The RF resonant loops and director coupling strip elements alternatively may be incorporated with the wireless tablet computer device itself.
