Abstract: An electronic device includes an antenna, an irremovable component, a removable component, an impedance matching circuit, and a controller. The impedance matching circuit is arranged in a first configuration corresponding to the removable component connected to the irremovable component. The impedance matching circuit has a first capacitor, a second capacitor, and a third capacitor. The controller is configured to arrange the impedance matching circuit in a second configuration corresponding to the removable component being disconnected from the irremovable component.
