Abstract
A novel dual-passband filter using the unit-cell (UC) composite right/left-handed (CRLH) coplanar waveguide (CPW) open-circuited stub and the UC electromagnetic bandgap (EBG) CPW short-circuited stub is proposed. The CRLH open-circuited and EBG short-circuited stubs in parallel connection are equivalent to the dual-passband lumped-element CPW resonators within the specific frequency range. The performance of a third-order dual-passband filter with Chebyshev responses is measured and validated by full-wave simulation.
