Design of a Terahertz Leaky-Wave Long-Slot Antenna Using Graphene
In this paper, a novel graphene-based leaky-wave antenna is presented. The frequency of the proposed antenna is in the terahertz range, and it is composed of a straight long slot covered with a graphene sheet. To tune the leakage constant along the slot, DC voltage biases are applied using gating pads. A transverse equivalent network model that includes the graphene slot structure is also presented. A design procedure for a lossy structure leaky-wave antenna with an unknown loss value is proposed. The antenna is designed and simulated in HFSS and CST software. An interesting feature of this antenna is the ability to control its radiation characteristics across its entire working frequency range through graphene conductivity tunability with DC voltage bias.
