This paper presents the possibility of employing an ionic polymer–metal composite (IPMC) actuator for coplanar waveguide fed antenna reconfiguration. Proposed antenna structure integrates defected ground structure (DGS) into the feeding line, which performs role of the band-reject filters, enhancing selectivity and shaping the frequency response. The IPMC strip acts as an electromechanical tuning element and lifts a separate substrate above the primary radiator. Such replacements alter the electromagnetic field distribution and lead to the operating frequency shift, offering a low-power alternative to conventional methods. With only 5V of bias voltage, operating frequency tuning rage is about 130%, from 2.61 GHz to 6.11 GHz, without bringing additional losses. The results confirm the feasibility of IPMC actuators for frequency tuning applications.
