A multi-band antenna assembly that is operable to receive and/or transmit signals at one or more frequencies generally includes at least two radiating elements, a transmission line coupled to each of the at least two radiating elements, and a tunable match resonator coupled to the transmission line. The tunable match resonator is operable to vary input impedance of a signal received and/or transmitted by the antenna assembly by changing an electrical field within the tunable match resonator.
