Abstract

A labyrinth resonator with defective ground structure (DGS) is introduced for designing a wide-band band-stop filter in order to adjust the resonating characteristics by varying the dimension of the structure to cover 2.75 - 10.30 GHz. A series of modified double-split ring resonators (DSRRs) are embedded into a 50Ω microstrip framework to attain a labyrinth structure. The Rogers RO- 3010, which has a succinct structure, is used as the substrate in the proposed wide-band band-stop filter. The realization of the architecture is explored both integrally and experimentally, and a complementary split ring resonator (CSRR) is introduced in the ground layer. The level of rejection of the filter in the stop-band region increases with the introduction of the CSRR. In addition, the filter is evaluated by applying the Nicolson-Ross-Weir approach at the filtering frequency. The effective electromagnetic parameters retrieved from the simulation of the S-parameters imply that the metamaterial structure exhibits negative refraction bands. With a promising design and wide range of double-negative characteristics, we propose a new type of filter which is suitable for a wide-band band-stop application.
