Abstract
A communication device and a detachable antenna with dynamic antenna tuning is provided. The detachable antenna comprises: an electrically insulating base; a main antenna and a first antenna element, at the base, respectively operable at independent first and second given frequencies. The device further comprises: a memory associating the first and second given frequencies; an antenna port configured to detachably receive the base of the detachable antenna; a second antenna element, at the antenna port, operable to wirelessly interact with the first antenna element when the base of the detachable antenna is received at the antenna port; a circuit configured to detect wireless interactions between the second antenna element and the first antenna element; and a controller configured to: select the first given frequency using the second given frequency, as detected via the circuit; and, thereafter wirelessly communicate via the main antenna operated at the first given frequency.
