    Abstract: A wireless communications device (102) includes a flip assembly 106 that includes a speaker (120) and that has a GPS antenna (104) mounted about a fa r edge. The flip assembly (106) further has a GPS RF amplifier (314) mounted adjacent to the GPS antenna (104) for amplifying signals received by the GPS antenna (104) and providing those amplified signals to a GPS RF stripline (312). The GPS RF stripline (312) includes a flexible RF stripline (404) to accommodate rotationally opening and closing of the flip assembly (106). Positioning of the GPS antenna (104) about the far edge of the flip assembly (106) removes the GPS antenna from a main housing assembly (108) of the wireless communications device (102) and provides for better GPS signal reception performance.

    Abstract: A multiband element antenna (120) 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 (100) that has a conductive chassis includes a flip up antenna (120) that pivots between an extended and a retracted position. The antenna (120) pivots at a point that is located on one edge of the top of the cell phone body (102). The conductive chassis of the flip cover (104) is grounded to the flip phone body (102) at a single point or single surface that is substantially opposite the antenna RF feed (122). Conductive surfaces of the cellular flip phone body (102) are grounded at a single point that is near the antenna RF feed point (122). This grounding arrangement has been found to control the flow of induced currents on the conductive portions of the flip cover (104) and body (102), thereby improving the performance of the device's antenna (120).

    Abstract: A portable communication device includes a first communication subsystem (102) and a second communication subsystem (104). The two communication subsystems operate in different frequency bands and use a common antenna structure. The antenna structure includes a fixed antenna element (110) and a retractable antenna (114) that may be electrically coupled to the fixed antenna element when moved to a fully extended position. The retractable antenna changes the impedance characteristics of the antenna structure substantially at the frequency used by the second communication subsystem, so a matching network (108) is switched in or out of the path between the second communication subsystem and the diplexer. A position detecting circuit (116) and switch controller (118) control operating of the matching network (108) depending on the position of the retractable antenna.

    Abstract: The invention concerns an antenna assembly (102) and a method (600) of operation thereof. In one arrangement, the antenna assembly can include a first antenna element (202) and a second antenna element (204), electrically disconnected from the first antenna element and a switching element (210) to selectively connect the first antenna element and the second antenna element. In another arrangement, the method can include the steps of sliding (604) the switching element to a first position to operate the antenna assembly in a first mode of operation and sliding (606) the switching element to a second position to operate the antenna assembly in a second mode of operation. As an example, in the first mode of operation, the antenna assembly can operate as a one-half wavelength antenna. In the second mode of operation, the antenna assembly can operate as a quarter wavelength antenna.
