Summary:This paper addresses the growing need for multifunctioning microwave components by proposing a miniaturized reconfigurable stopband filter. The compact size is the outcome of the novel metamaterial split-ring resonator used for realizing this filter. Six PIN diodes are used to achieve real-time frequency and mode reconfigurability. This filter is designed to reject three important frequencies in wireless communication systems: 1.9, 2.4, and 3.6 GHz. Moreover, depending on the use, it is possible to reject one, two, or all the three frequencies, which resulted in seven different cases with three possible modes: single, dual, or triple stopbands. A prototype was manufactured for this filter, and strong agreement between simulation and measurement results is observed. Due to its target bands, this reconfigurable stopband filter is suitable for various cellular communication technologies from 3 G and 4 G up to 5 G and many other S-band applications.
