Description
Summary:The design and construction of two Metamaterial (MTM) directional filters (DF) for multiplexing applications at 900 MHz is presented. The four‐port filters are realized using composite‐right‐left‐handed (CRLH) closed‐loop resonators, which present small dimensions and suppression of harmonic resonances due to the zeroth‐order resonance produced by MTM's. The first filter uses two conventional transmission lines (TL) between resonators to generate the necessary constructive‐destructive interference for directional behavior. The second design is further miniaturized by a CRLH TL. The simulated responses are compared with measured data showing good agreement. © 2009 Wiley Periodicals, Inc.
