Summary:
Two wideband left-handed (LH) transmission lines are presented. A pure LH transmission line (PLH TL) materialized by a defected ground structure with an inter-digital capacitor on a microstrip line has a wide LH propagation region without a right-handed (RH) branch in the reduced Brillouin zone. Another is a broadband LH rectangular waveguide utilized by a shorted stub and twisted Eplane posts. Two LH transmission lines which can be represented by crossly connected circuits have wide LH fractional bandwidths of 143.5% (PLH) and 26.5% (LH waveguide), respectively.
