Abstract
In this paper, a hexagon shaped antennas is designed for covering 5.8GHz band for Wi-Fi applications and covering 6GHz and above up to 8GHz for 5G applications. The proposed antenna is surrounded by metamaterial (MM) unit cells. Five metamaterial unit cells are used and three of the alternate MM unit cells connected to the radiating element via PIN diodes and the antenna maintained a partial ground with slot. The MM unit cells follows hexagon shaped rings. Roger 3006 flexible material with thickness 1.27mm and dielectric constant 6.15 is used as substrate. The proposed antennas is analyzed for the frequency range 4GHz to 9GHz and the comparative analysis is presented with the help of the reflection coefficient, VSWR, radiation patterns and other antenna parameters for different switching conditions.
