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 ...

Negative-refractive-index transmission-line metamaterials and enabling electromagnetic applications
(2004)The negative-refractive-index (NRI) metamaterials, for which the permittivity and permeability are simultaneously negative, were discussed. The results for two RF/Microwave devices and structures, based on transmission-line ...

Reconfigurable Bandwidth Bandpass Filter with Enhanced Out-of-Band Rejection Using π-Section-Loaded Ring Resonator
(2018)A novel ring resonator bandpass filter with reconfigurable bandwidth with central frequency at 2.4 GHz is demonstrated. Theoretical analysis for computing the resonant frequencies is shown, and the design approach of ...

Wideband BPF using quadruple-mode ring resonator loaded with short-circuited stubs and Γ-shaped band-stop sections
(2017)In this letter, a compact, wideband bandpass filter with 31% 3-dB bandwidth, with very sharp roll-off characteristics, low insertion loss of 0.45 dB, high return loss greater than 25 dB, and improved out-of-band performance, ...
