Compact EBG-Backed Planar Monopole for BAN Wearable Applications
Abbasi, M. A. B.; Nikolaou, S. S.; Antoniades, Marcos A.; Nikolić Stevanović, M.; Vryonides, P. (2017)This paper presents a planar monopole backed with a 2 × 1 array of electromagnetic bandgap (EBG) structures. The reflection phase of a single EBG unit cell has been studied and exploited toward efficient radiation of a ...

Conformai wearable monopole antenna backed by a compact EBG structure for body area networks
Antoniades, Marcos A.; Abbasi, M. A. B.; Nikolic, M.; Vryonides, P.; Nikolaou, S. (Institute of Electrical and Electronics Engineers Inc., 2017)A compact planar monopole antenna backed by an electromagnetic bandgap (EBG) structure is presented. The antenna is conformal to the human body and is intended for wearable applications in wireless body area networks. It ...

A high gain EBG backed monopole for MBAN off-body communication
Abbasi, M. A. B.; Nikolaou, S.; Antoniades, Marcos A. (Institute of Electrical and Electronics Engineers Inc., 2016)This paper discusses the use of an EBG array structure as a director for efficient radiation of a printed monopole antenna. A planar monopole printed on a partially grounded substrate is loaded with a 3×2 EBG structure, ...

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 ...
