Designing Graphene-Based Antenna for Terahertz Wave Ablation (Twa) System

Abstract

Cancer is one of the most feared health problems today. Studies on cancer diagnosis and treatment are carried out intensively. In this study, a graphene-based antenna is proposed for cancer diagnosis and treatment with THz radiation therapy, which is a relatively new radiation technique. A graphene-based two-layer monopole antenna is designed for 1.65THz operation frequency. To change the bandwidth and radiation pattern without changing the operating frequency, a graphene ring is placed on the SiO2 substrate (2nd layer).Antenna performance is analyzed for reflection coefficient, realized gain, E-Field. The proposed antenna is obtained approximately %4 bandwidth. A peak gain of 8.52 dB is achieved at 1.65THz within the bandwidth. Antenna design is done in Computer Simulation Technology Studio Suite. It is expected that the results of the THz antenna will make a significant contribution to healthcare applications. The cancer treatment with THz is cheap, easy, and can be used without causing discomfort in patients.
