A compact crossover using NRI-TL metamaterial lines
(2012)A compact NRI-TL metamaterial branch-line crossover is presented that has an area of λ/36 × λ/12, and is a factor of 81 times smaller than its analogous transmission-line counterpart. Circuit simulations reveal that it ...

A compact tri-band monopole antenna with single-cell metamaterial loading
(2010)A compact tri-band planar monopole antenna is proposed that employs reactive loading and a defected ground-plane structure. The reactive loading of the monopole is inspired by transmission-line based metamaterials (TL-MTM), ...

Compact, wideband and multiband antennas based on metamaterial concepts
(2010)In this review article, various antenna designs that are based on metamaterial concepts are presented which have been developed at the University of Toronto. Specifically, several antennas that are based on the zero-index ...

A multi-band NRI-TL metamaterial-loaded bow-tie antenna
(2011)A compact, fully-printed and low-profile bow-tie antenna is proposed, which exhibits multi-band performance by loading a reference bow-tie antenna with series capacitive gaps and shunt inductive strips, to form an asymmetric ...

A multiband monopole antenna with an embedded reactance-cancelling transmission-line matching network
(2010)A series reactance-canceling (SERCA) transmission-line (TL) matching network is proposed, which replaces the series resonant circuit of a double-tuned Wheeler matching network with a λg/2 TL in order to achieve a broadband ...

A NRI-TL metamaterial-loaded bow-tie antenna
(2011)A fully-printed and low-profile bow-tie antenna is proposed, which exhibits multi-band performance by loading a bow-tie antenna with series capacitive gaps and shunt inductive strips, to form an asymmetric two unit-cell ...
