Abstract: An antenna is provided with improved ruggedness and flexibility through the use of an embedded substrate with impedance matching circuitry disposed thereon, and a flexible electrical interconnect. The flexible electrical interconnect is coupled between the substrate and an antenna connector. The antenna comprises a first top flexible section having the flexible radiator element, a second stiff section comprising the impedance matching circuit for multi-band operation, and a third lower flexible section comprising the flexible electrical interconnect. Portable radio products incorporating the antenna can now provide multiband capability along with protection against drop.

Abstract: A method and wireless device for updating at least one cryptographic security key (116) associated with a wireless device (104) and an authentication module (108). An over-the-air programming message comprising security key update information is received (804) from an information processing system (118). The security key update information is processed (808). At least one new security key is extracted from the security key update information in response to the processing (806). At least one existing security key (116) is updated with the at least one new security key (124) that has been extracted.
