Abstract
In this paper, a novel tunable antenna using graphene-based artificial magnetic conductor (AMC) is proposed and investigated. The resonance frequency of the AMC ground plane can be electrically tuned by applying a gate voltage. A bowtie-shaped antenna is mounted above the 15×15 AMC units. It is observed that the operating frequency of the antenna system shifts in a large range when varying the external electric field. The bandwidth of the antenna system can reach as high as 47% with a gain higher than 9 dB.
