Abstract

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 show the feasibility of the proposed concept. The experimentally verified response of the antenna is also compared to full-wave simulation results.
