Abstract

A Polydimethylsiloxane (PDMS) based antenna is designed for skin tumor detection. The antenna functions at 2.45 GHz with a bandwidth of 2.30–2.64 GHz working in the ISM (Industrial, Scientific, and Medical) band. The size of the antenna is 40 × 40 × 1 mm3. This antenna detects tumors in the skin by considering the variations in values of the E-field, J-surf, and H-field. Various analyses such as the distance between the patch and stacked layer skin phantom for different tumor sizes and input power to the antenna are changed and antenna performance is observed. A significant amount of changes is attained which denotes the presence of the tumor. The proposed antenna is fabricated and the corresponding results are analyzed in the Anechoic Chamber. The antenna has an efficiency of 99 % with a Specific Absorption Rate of 1.3846 W/kg which is lower than 1.6 W/kg as per the recommendations of FCC standard.

利用基于聚二甲基硅氧烷的可穿戴天线进行肿瘤检测分析

为皮肤肿瘤检测设计了一种基于聚二甲基硅氧烷（PDMS）的天线。该天线的工作频率为 2.45 GHz，带宽为 2.30-2.64 GHz，工作在 ISM（工业、科学和医疗）频段。天线尺寸为 40 × 40 × 1 mm3。该天线通过考虑 E 场、J 场和 H 场值的变化来检测皮肤上的肿瘤。对不同肿瘤大小的贴片和叠层皮肤模型之间的距离以及天线的输入功率进行了各种分析，并观察了天线的性能。观察到的大量变化表明肿瘤的存在。在消声室中制作了拟议的天线并分析了相应的结果。天线的效率为 99%，比吸收率为 1.3846 W/kg，低于 FCC 标准建议的 1.6 W/kg。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
