In this paper, the design of an ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna based on metamaterial is proposed. The antenna is designed to achieve dual band-notched and high isolation using metamaterials. The traditional split ring resonators (SRRs) are used to achieve the band-notched effect and a new type of SRR is used to reduce the mutual coupling at both 3.1 GHz and 10 GHz...
We have simulated a circular waveguide loaded with double-negative metamaterials (DNMs) and single-negative metamaterials (SNMs) characterized by the Drude and Lorentz models respectively. The simulation results clearly show a passband in a desired frequency range in which both the permittivity and permeability of the DNMs have negative real parts, whereas a stopband appears for the SNMs cases. The...
