Abstract

In this work, a single port toothed log periodic antenna (TLPA) based on Hilbert curve graphene artificial magnetic conductor (AMC) is proposed for frequency band (0.1–10) THz operation. The bandwidth and resonance frequency of the proposed antenna can be tuned by changing the connected DC voltage which leads to variation in the chemical potential of graphene. The radiating element of the TLPA is gold patch placed on Hilbert curve graphene AMC. Exponential taper is used to satisfy impedance matching between the antenna and the feeder over the required frequency range. The simulation results reveal that 100 % of the frequency range satisfies s_11<-10 dB when chemical potential is1eV.
