The implementation of a frequency-reconfigurable antenna with the use of a moving feeding technique is described in this letter. A flexible coaxial feed is attached to the main microstripline feed of a perturbed Sierpinski monopole gasket, and it slides with the help of computer-controlled motor mechanism. Single and multiple operational frequencies are observed during the movement of the feed. The antenna and the reconfigurable system were designed, implemented, and experimentally verified to
