Compact ultra-wideband metamaterial antenna by Alhawari, Adam Reda Hasan, Ismail, Alyani, Mahdi, Mohd Adzir

“…The proposed antenna is composed of three-unit cells of left-handed metamaterial (LHM) where these LHM unit cells are composed of a combination of modified octagonal spiral resonator (OSR), octagonal split-ring resonator (OSRR), capacitance-loaded strip (CLS), and wire that exhibit negative electrical permittivity (ε) and negative magnetic permeability (μ) simultaneously. A trident-shaped feeding strip is used to feed all the three LHM unit cells respectively; which are united into a single line feeding strip on top of substrate surface, whereas the wire and ground plane are deposited in the bottom of substrate surface. …”
