US Patent:

6873294, Mar 29, 2005

Filed:

Sep 9, 2003

Appl. No.:

10/658183

Inventors:

Eric A. Anderson - Crystal Lake IL, US
Benjamin O. White - Crystal Lake IL, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01Q001/26
H01Q001/38

US Classification:

343702, 343700 MS

Abstract:

An apparatus and a method for reducing magnetic field in near-field by presenting high impedance at an operating frequency band are disclosed. A conducting element (), which is suspended substantially parallel to a first side () of a printed circuit board () of a wireless portable communication device () over an electrically grounded conductor (), forms a reactive element. The reactive element provides high impedance at operating frequencies of the wireless portable communication device and diverts radio frequency currents from the first side of the printed circuit board to the second side of the printed circuit board such that a magnetic field produced by the radio frequency currents on the first side of the printed circuit board is reduced in the near-field.

Appl. No.:

13/368360

Inventors:

Benjamin O. White - Crystal Lake IL, US
Jin D. Kim - Pleasant Prairie WI, US
Sang Eun Lee - Lake Forest IL, US

Assignee:

MOTOROLA MOBILITY, INC. - Libertyville IL

International Classification:

G01S 19/40

US Classification:

34235723

Abstract:

A method and chipset for tracking a global navigation satellite system (GNSS) within the constraints of an indoor facility. The method includes receiving assistance information on the GNSS on a mobile communication system; and sorting orbiting satellites within the GNSS by elevation angles. Additionally, lower elevation satellites are correlated within the GNSS prior to correlating higher elevation satellites.

Motorola Mobility LLC - Libertyville IL

International Classification:

H04W 88/06

US Classification:

4554261, 4555521

Abstract:

Systems and methods are provided for an antenna switch module () for an electronic device () including wireless communication circuitry () and an antenna () configured to transmit and receive signals over a plurality of frequency bands. The antenna switch module may include a plurality of antenna switches () positioned in series and configured to pass signals between the antenna and wireless communication circuitry and to selectively operate in one of the bands. The first antenna switch () may include a plurality of pins () arranged in a first configuration, and the second antenna switch () may include a plurality of pins () arranged in a second configuration that is a mirror image of the first configuration. The antenna switch module may further include a plurality of non-overlapping signal paths () configured to selectively deliver signals between the antenna switches, each signal path being associated with a respective band.
