Abstract:

A wireless communications device () includes a flip assembly that includes a speaker () and that has a GPS antenna () mounted about a far edge. The flip assembly () further has a GPS RF amplifier () mounted adjacent to the GPS antenna () for amplifying signals received by the GPS antenna () and providing those amplified signals to a GPS RF stripline (). The GPS RF stripline () includes a flexible RF stripline () to accommodate rotationally opening and closing of the flip assembly (). Positioning of the GPS antenna () about the far edge of the flip assembly () removes the GPS antenna from a main housing assembly () of the wireless communications device () and provides for better GPS signal reception performance.

Filed:

Jul 16, 2004
Appl. No.:

10/892858
Inventors:

Jan-Ove U. Mattsson - Plantation FL, US
Paloma I. Lampert - Plantation FL, US
David Hartley Minasi - Fort Lauderdale FL, US
Assignee:

Motorola, Inc, - Schaumburg IL
International Classification:

H01Q 1/24
US Classification:

343702, 343876
Abstract:

An antenna structure () that includes a Planar Inverted-F Antenna (PIFA) () and an extendable portion such as a whip element (). The PIFA () operates normally when the extendable portion () is retracted and upon extension, an electrical contact is made between the extendable portion () and the end () of the PIFA () that is electrically opposite, i. e. , furthest along the electrically conductive path of the PIFA, from the feed structure () for the PIFA (). The electrical length of the composite antenna () is then substantially equal to the sum of the electrical length of the PIFA () and extendable portion (). An embodiment disconnects the ground path of the PIFA feed structure upon extension of the extendable portion () to provide constant input impedance.

Abstract:

A multiband element antenna () used in combination with a unique metal chassis design that enhances antenna performance and that enables the design of a compact and efficient antenna system. A cellular flip phone () that has a conductive chassis includes a flip up antenna () that pivots between an extended and a retracted position. The antenna () pivots at a point that is located on one edge of the top of the cell phone body (). The conductive chassis of the flip cover () is grounded to the flip phone body () at a single point or single surface that is substantially opposite the antenna RF feed (). Conductive surfaces of the cellular flip phone body () are grounded at a single point that is near the antenna RF feed point (). This grounding arrangement has been found to control the flow of induced currents on the conductive portions of the flip cover () and body (), thereby improving the performance of the device's antenna ().

MOTOROLA, INC. - SCHAUMBURG IL
International Classification:

H04L 27/06
US Classification:

375344000
Abstract:

A method and apparatus to correct a periodic signal, such as a frequency reference, based upon another frequency reference. A lower accuracy frequency signal generator () provides an uncorrected frequency reference signal () to a frequency corrector (). Frequency corrector () counts cycles of a frequency reference signal (), as generated by a higher accuracy reference generator () for a time period derived from the uncorrected frequency signal. Based upon the cycles counted, pulses are added or removed from the uncorrected frequency signal () to produce a corrected frequency signal (). A ratio of pulses to be removed from the uncorrected frequency signal () is determined from the number of cycles counted and a counter arrangement is provided to automatically remove the required ratio of pulses from the uncorrected frequency signal ().
