Arbitrary length zero-phase substrate integrated coaxial lines using NRI-TL metamaterials
Quddious, A.; Nikolaou, S.; Antoniades, Marcos A. (Institute of Electrical and Electronics Engineers Inc., 2017)Arbitrary-length zero-degree phase-shifting lines are presented at X-band that are based on negative-refractive-index transmission-line (NRI-TL) metamaterials implemented in substrate integrated coaxial line (SICL) technology. ...

Reconfigurable Bandwidth Bandpass Filter with Enhanced Out-of-Band Rejection Using π-Section-Loaded Ring Resonator
Arain, S.; Vryonides, P.; Abbasi, M. A. B.; Quddious, A.; Antoniades, Marcos A.; Nikolaou, S. (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
Arain, S.; Vryonides, P.; Abbasi, M. A. B.; Quddious, A.; Antoniades, Marcos A.; Nikolaou, S. (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, ...
