Gain enhancement of microstrip antenna using artificial magnetic conductor
(2020) Hamrioui, Fatma Zohra; Bouhafs, Djazia; Azrar, Arab (supervisor)
The aim of this project is to design a dual band monopole antenna based on AMC reflector. In contrast to many studies on single band low profile antenna design; the work focuses on improving the radiation performance of CPW monopole antenna within two operating bands simultaneously which is typically a challenge due to the mutual influence between the antenna and the AMC surface.
Design of metamaterials dual-band bandpass filter for Wimax applications
(2020) Debili, Seif El Islam Seif El Islam*; Zaboub, Oussama Oussama; Challal, Mouloud (supervisr)
This work suggests the design of a dual-band bandpass filter (BPF) based on metamaterial triangular split ring cell. The proposed structure is designed using CST software . It is found that the suggested structure is developed to have two passbands at central frequencies 3.5 GHz and 5.8 GHz intended for WiMAX communication system. The design was performed in FR4 substrate with relative dielectric constant of 4.3, thickness of 1.63 mm and a dialectic loss tangent of 0.017 , the software used is CST microwave studio ..
