Experimental Demonstration of Nonreciprocal Phase-Shift Composite Right/Left-Handed Transmission Lines Using a Ferrite-Rod-Embedded Substrate

Transmission characteristics of nonreciprocal phase-shift composite right/left-handed transmission lines are experimentally investigated along with comparison to the numerical simulations. The line is composed of a microstrip line using a normally magnetized ferrite rectangular rod embedded into a dielectric substrate just below the center strip. It is experimentally verified that nonreciprocity in the amplitude of the transmission coefficients is negligibly small, whereas the nonreciprocity in the phase is still kept of the same order as previously reported.
