Miniaturization of monopole antenna using high refractive index metamaterial loading

摘要

In this article, miniaturization of the wire monopole antenna with the help ofhigh refractive index (HRI) metamaterial is presented. For the first time, HRImedium is realized by using the array of single ring split ring resonator. Bysurrounding the wire monopole with the array of SR-SRRs, the effective wavelengthis squeezed in the vicinity of the near field dominance. By the loadingof the monopole with such an HRI medium, the size of the antenna is reducedfrom 29.5 to 16 mm, without any deformation in the current distribution andradiation pattern corresponding to the fundamental resonance. The simulatedand measured results are agreed to the same.
