Enhancing the Performance of Polygon Monopole Antenna Using Graphene/TMDCs Heterostructures

In this letter, Laser Induced Graphene (LIG) as a low cost and versatile technique, was utilized to fabricate coplanar waveguide fed polygon monopole antenna on glass substrates. A modified LIG-MoS2 heterostructure based antennas were also fabricated and characterized. The formation of the graphene and the successful realization of the hybrid structures were examined and confirmed by several techniques including SEM, Raman and EDX. The conductivity as well as the reliability over large areas were demonstrated for both materials, concluding a significant improvement of LIG-MoS2 heterostructure over graphene antenna. Consequently, the two proposed antennas have shown up to 30% enhancement in gain with respect to a reference fabricated copper-based antenna.
