Abstract
An apparatus comprising: a conductive member configured to receive an antenna and to form a non-conductive region between the conductive member and a ground member; and a switch having a first closed configuration and a second open configuration, the first closed configuration being configured to couple the conductive member to the ground member across the non-conductive region and to provide a first current path having a first electrical length and a first resonant frequency, the second open configuration being configured to provide a second current path having a second electrical length and a second resonant frequency, the second resonant frequency being lower than the first resonant frequency.
