Abstract:
This paper presents a coplanar composite right-left handed zeroth-order resonator (CRLH CPW ZOR) and a coplanar composite right-left handed transmission line (CRLH CPW TL). These devices are realized using an elementary cell designed in a coplanar waveguide configuration on alumina substrate. Additional lumped elements are carried out with an interdigital series capacitor and a short-circuited stub inductor as a shunt. The CRLH CPW ZOR is fabricated and analyzed using equivalent circuit modeling and three dimensional finite element method. The proposed devices are fabricated and measured. The resonator has a measured insertion loss of 2.7 dB and a return loss better than 13dB. The length of the proposed device is only 5.2 mm; this very small size compared with a traditional half wave resonator shows the interest of this kind of approach.
