Design of microwave devices based on a combination of traditional right-handed transmission line sections with positive dispersion and metamaterial left-handed transmission line sections with negative dispersion is considered. Compared to homogeneous transmission lines, the use of cascaded line sections gives additional degrees of freedom for the design of microwave devices with enlarged functionality...
Additional degrees of freedom in a design of miniature microwave devices can be provided by a combination of right-handed (RH) and left-handed (LH) transmission lines (TL), which differ in dispersion characteristics. We present some examples of such devices: planar resonator and filter with suppressed spurious response as well as a miniaturized matched balun and broadband digital phase shifters. Whereas...
