摘要
提出了一种用于癌症检测和治疗的超宽带维瓦尔第天线。该天线在自由空间4.63 GHz (3.13 GHz-7.76 GHz)带宽范围内工作在4.76 GHz的谐振频率。此外，该天线在自由空间条件下具有高达81.34%的辐射效率和5.81 dB的增益。天线的整体尺寸为110.46 x 96.77 x 1.67 mm3。该天线采用1.6 mm厚的FR-4介电基片进行模拟，因为它具有成本效益且易于获得。此外，建立了一个六层生物组织模型，包括皮肤、脂肪、外皮质骨、松质骨、内皮质骨和肌肉，肿瘤半径为10mm，以评估天线在癌症检测和治疗中的性能。在仿真中，为了避免皮肤烧伤和其他副作用，所提出的天线和所提出的幻影模型之间保持2.5 mm的特定间隙。由于肿瘤组织的SAR值高于正常健康组织，因此肿瘤细胞被发现并被杀死。
Design and Simulation of an UWB Vivaldi Antenna for Cancer Detection and Treatment
An UWB Vivaldi antenna is proposed for cancer detection and treatment. The antenna operates at the resonant frequency of 4.76 GHz within the bandwidth of 4.63 GHz (3.13 GHz-7.76 GHz) in free space. In addition, the antenna possesses a high radiation efficiency of 81.34% and a gain of 5.81 dB in free space condition. The overall dimension of the proposed antenna is 110.46 x 96.77 x 1.67 mm3. The antenna is simulated with 1.6 mm thick FR-4 dielectric substrate since it is cost-effective and easily available. Furthermore, a six-layer biological tissue model comprising of skin, fat, outer cortical bone, cancellous bone, inner cortical bone, and muscle with a tumor of 10 mm radius is modeled to assess antenna performance for cancer detection and treatment. In simulation, a specific gap of 2.5 mm is maintained between the proposed antenna and the proposed phantom model in order to avoid skin burn and other side-effects. Cancerous cells in tumor are detected and killed because of higher SAR value of the cancerous tissue than the normal healthy tissue.
