    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: A multi-frequency internal antenna apparatus (10) for a clamshell type electronic device includes a flexible circuit (20) that electrically couples circuitry between the main housing (12) and flip housing (14). A conductive element (36) is disposed on the main housing (12) and tuned to be electrically resonant above the operating frequencies of the electronic device. The conductive element (36) is disposed in proximity to the flip housing (14) in the open position and is electrically coupled at a high impedance point to the flexible circuit (20) and subsequently to the circuitry in the flip housing. When the movable flip housing is in the open position and being held by a user, the circuitry in the movable flip housing forms a secondary conductive element providing dipole characteristics that tunes the combined conductive elements to the operating frequencies of the electronic device.

    Abstract: A Parasitic Element ( 202 ) for use in combination with a Planer Inverted "F" Antenna (PIFA) ( 100 ) that creates an additional band of efficient operation for the combined antenna structure ( 200 ). The parasitic element ( 202 ) is able to be made to conform to surfaces ( 704 ) that are near the PIFA, such as of a case ( 704 ) of a cellular telephone ( 706 ). The parasitic element ( 202 ) is positioned so as to radiantly couple with the PIFA ( 100 ) in order to create the additional band of efficient operation. A parasitic element ( 202 ) is used with a dual band PIFA that operates in two RF bands, such as in the region near 800 MHz and 1.9 GHz, and adds a third band such as in the region near 1.575 GHz to support reception of Global Positioning System signals. This parasitic element ( 202 ) can conform to a case ( 704 ) of the cellular telephone ( 706 ).
