摘要

本文提出了一种新型的石墨烯基漏波天线。所提出的天线的频率在太赫兹范围内，它由一个覆盖着石墨烯片的直长槽组成。为了调整沿槽的泄漏常数，使用门控垫施加直流电压偏置。提出了包含石墨烯槽结构的横向等效网络模型。提出了一种损耗值未知的有耗结构漏波天线的设计方法。在HFSS和CST软件中对天线进行了设计和仿真。这种天线的一个有趣的特点是能够通过石墨烯导电性和直流电压偏置来控制其整个工作频率范围内的辐射特性。

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.
