This paper presents a new method to improve isolation between two loop antennas with absorber cells exhibiting negative permittivity and permeability at the aimed frequency of 2.45 GHz. The metamaterial (MTM) unit cell was constructed by two open complimentary split ring resonator (OCSRR) and a split ring resonator (SRR) arrangement. The proposed antenna structures were composed of two loop antennas...
This paper presents a compact double negative metamaterial (MTM) absorber unit cell four-element arrayed electric-LC (ELC) resonators. Overall size of the proposed unit cell is 9mm × 9mm × 2mm. The proposed four-element arrayed ELC resonator where the external magnetic field is normal to the plane of the ELC resonator substrate, and the electric field is parallel to the capacitor plate exhibit a negative...
