Publication number: 20200127380Abstract: An antenna includes an elongated conductive strip to which at least one capacitive element of adjustable capacitance and at least one inductive element are electrically coupled. The at least one capacitive element is coupled between the strip and ground. The at least one inductive element is switchable in parallel with the at least one capacitive element. The elongated conductive strip is integral with a periphery of a device shell. Adjustment of capacitance and switching of inductance is dependent on device operation.Type: ApplicationFiled: October 15, 2019Publication date: April 23, 2020Applicant: STMicroelectronics (Tours) SASInventor: Benoit BONNET
