Design of Twin-slot Radiator Beam-Forming Antenna Using Metasurface

Abstract

Designing an antenna is always challenging because there is a tradeoff between the gain and the size. More specifically to design an antenna for wireless data communication in ISM band with less interference, low power consumption. To address these issues, this paper proposes a twin-slot radiator for beam-forming with high gain. The antenna operating at 2.4GHz consists of a two-layer stack with a twin-slot radiator and a superstrate separated by air medium. The metamaterial structure is excited with different phase delays through the twin-slot fed radiator to radiate the antenna beam in a specific direction. The performance analysis of the designed antenna is studied by simulation and measurement setups.
