Abstract

Broadside coupled coplanar waveguides are used to realize a composite right/left-handed transmission line, which is characterized by antiparallel group and phase velocities. The transmission line design depends on the electromagnetic coupling between coupled lines. The broadside coupled coplanar waveguides was chosen to achieve tight coupling with practical dimensions, which reflects an enhancement in the bandwidth. Experimental verification for the design is demonstrated with good agreement to the simulated values. The proposed composite right/left-handed transmission line has a broad bandwidth.
