Abstract
This paper reports design and rigorous analysis of frequency reconfigurable graphene-based dipole antenna over AMC surface. Frequency reconfigurability has been introduced using electric field gating. The AMC has been designed with 90° reflection-phase bandwidth from 2 THz to 3 THz. The proposed antenna geometry is highly miniaturized due to propagation of extremely confined TM surface waves and it has good input matching with THz source. Gain and efficiency of the proposed antenna obtained through simulation are: 6.11 dB and 40.5 % respectively at a chemical potential equal to 1 eV. This antenna can be a good candidate for nanoscale wireless communication at THz frequencies.
