Design of a Novel Nanometric Graphene Pentagone Patch Antenna Array for Terahertz Transmission

Abstract

This paper presents an original design of nanometric pentagon patch array in the terahertz band. The materiel used for the patch is the graphene, it has a very important electronics properties and can be used to fabricate printed antennas with very low profile. In our work, we obtained frequencies resonant of proposed antenna by changing substrates materials: polyimide, PTFE, Rogers RO4003C and Rogers RO3003. The antenna resonates at four different frequencies: 4.84, 5.11, 5.15, 5.23 THz. A Graphene pentagon patch antenna array is designed for bandwidth and gain enhancement. We obtained a very large bandwidth of 1109.6 GHz and 8dB of gain with the use of Rogers RO3003 material substrate which is very satisfactory in terahertz band transmission.
