Gain enhancement of microstrip patch antenna using low loss negative refractive index metamaterial superstrate
A novel microstrip patch antenna (MPA) based on planar negative refractive-index metamaterial is proposed. It is demonstrated that the proposed nested split ring resonator (SRR) structure metamaterial yields an effective refractive index that equal to negative value over the frequency range of 770 M...
