Analytical Study of Tunable Bilayered-Graphene Dipole Antenna

Abstract

The focus of this research is the mathematical study of the characteristics of a planar microstrip dipole antenna with a bilayer graphene semiconductor as the transmission line. In any microstrip structure, there is a transmission layer, dielectric layer, and ground layer. In this study, there will be a high impedance metal layer on top of the transmission line in segments along the length of the antenna. Like a double gate contact of a MOSFET transistor, this high impedance layer and ground plane will provide a vertical electric field to create a bandgap in the BLG layer. This study will use bandgap tuning in the BLG to provide theoretical data on tuning a dipole antenna in different sequences along the antenna length. Selected sequences will be chosen in this study to determine the change in radiation patterns and magnitudes in the far field region The results of the data in this paper can benefit radar, munition proximity fuzes, and mobile wireless communication devices.
