A Criss-Cross Metamaterial Based Electrically Small Antenna

Metamaterials (MM) have been able to make their position strong in the world of electromagnetic in the past years. Researchers have come up with several novel shapes which behave as metamaterials. The characteristic parameters of permittivity ε and the permeability μ were extracted by doing several experimentations and found them to be negative. This paper presents such a new shape namely Criss-Cross whose negative behaviour has been discussed. The mathematical modelling for finding the transmission and reflection coefficient of the wave in such medium has also been derived. Further, it has been used to reduce the size of a rectangular patch antenna.
