In the design, different stages of parallel-coupled microstrip line and other stages with a Modified Complementary Split Ring Resonator (MCSRR)—a concept proposed here for the first time—are adjusted to obtain the desired response with broadband, sharp rejection, low insertion loss, and low return loss. Full wave simulation results as well as measurement results from fabricated prototypes are presented, showing good agreement.Theproposed technique offers a new alternative to implement low-cost high-performance filter devices, applicable to a wide range of communication systems.4 p.application/pdfeng© 2013 J.
