Abstract

In this article, a method to enhance the radiation characteristics of a slot antenna by using an electric metasurface as a high refractive index superstrate has been presented. The gain enhancement mechanism described here uses the phenomena of enhanced space field by increasing the effective aperture of the antenna, resulting from increase in effective refractive index of the metasurface. As a fundamental constituent of the superstrate, a unit cell of the metasurface composed of symmetrically placed triple pairs of split-ring resonators is introduced. The unit cell of such metasurface has been configured to realize a high refractive index by using the principle of nearest-neighbor coupling. An equivalent circuit model is developed to understand the influence of coupling on the effective refractive index of the metasurface. The presence of the metasurface as a superstrate enhances the broadside gain of the slot by 8.71 dB and the efficiency by 20.35 %. The total height of the proposed configuration is 0.237 λ 0 where λ 0 is the free space wavelength at the resonance frequency of the slot antenna.
