The THz antennas play important role in various applications such as medical sensing. In this paper, a compact THz antenna based on graphene loads is presented. The basic antenna is a slot antenna and it works at 0.8 THz and the graphene loads in arc-shaped are added to the basic structure and it reduced the operation frequency to 0.65 THz. It means that the graphene is useful for miniaturizing the proposed antenna and also the bandwidth of the antenna increased to 56% for the chemical potential of the 0.8 eV. In addition, the graphene loads are controlling the surface current of the antenna which is important for increasing the Q-factor. Furthermore, this study shows how the chemical potential and relaxation time of the graphene can be used for increasing the Q-factor of the antenna. Based on recent research in the THz spectrum, this antenna is used for detecting the breast cancer cell as an early detection cancer system. In brief, the graphene loads are used for controlling the electric field and it is considered for increasing the bandwidth and Q-factor which are important for cancer detection.

太赫兹天线在医疗传感等各种应用中起着重要作用。本文提出了一种基于石墨烯负载的紧凑型太赫兹天线。基本天线是缝隙天线，工作频率为0.8 THz，并将弧形石墨烯负载添加到基本结构中，并将工作频率降低到0.65 THz。这意味着石墨烯可用于使所建议的天线小型化，并且对于0.8 eV的化学势，天线的带宽也增加到56％。另外，石墨烯负载控制着天线的表面电流，这对于增加Q因子很重要。此外，这项研究表明如何利用石墨烯的化学势和弛豫时间来增加天线的Q因子。根据THz频谱的最新研究，该天线用于检测乳腺癌细胞，作为早期检测癌症系统。简而言之，石墨烯负载被用于控制电场，并且被考虑用于增加带宽和Q因子，这对于癌症检测是重要的。
