Graphene-Inspired THz Frequency-Reconfigurable Antennas for Biomedical Applications
In this manuscript, a novel graphene-based frequency reconfigurable antenna for terahertz applications is proposed. The antenna covers the frequency band from 2 THz to 4 THz with an overall size of $200 \mu \mathrm{~m} \times 350 \mu \mathrm{~m}$. The designed antenna has a compact structure and low profile. The shape of the radiator is modified from a merged elliptical structure, and the feed line is tailored using hexagonal slots. A Split Ring Resonator (SRR) is incorporated to achieve dual-band operation and enhance near-field confinement. The impedance bandwidth achieved is 4 THz, and the antenna gain is above 3 dBi. The radiation characteristics are directional within the desired operating bands.
