Abstract

The objective of this paper is to present a study of the graphene waffle-typed antenna, worked for skin-typed medical applications such as microwave breast imaging. The antenna is designed to operate at 402-405 MHz medical implant communication service band (MICS). The antenna is required to be flexible or bendable enough for a curve-fit into the patient skin, especially at the chest location. The DuPont Kapton with the thickness of 0.25 mm is used as the substrate. The graphene conductor is used due to its flexibility. The antenna is designed by using XFDTD program with two different superstrate materials, the Kapton and household silicon. The genetic algorithm is applied for tuning the antenna parameters. The curved model is tested on the chest with different facets curved. The return losses are compared, and the I-g average specific absorption rate, SAR, are defined for the maximum input power available. The antenna with 32 curved facets and 22.5 degree bending model were compared to the conventional style. The maximum input powers for the antenna with Kapton and silicon superstrates are 4.43 mW and 4.46 mW, respectively.

用于皮肤型医疗应用的柔性石墨烯华夫饼型天线

本文的目的是介绍一种用于皮肤型医学应用的石墨烯华夫饼型天线的研究，如微波乳房成像。该天线设计工作在402-405兆赫医疗植入通信服务频段(MICS)。这种天线需要足够灵活或可弯曲，以便与患者的皮肤，特别是胸部的皮肤形成曲线。采用厚度为0.25 mm的杜邦卡普顿作为基材。石墨烯导体因其柔韧性而被使用。采用卡普顿和家用硅两种不同的上盖材料，采用XFDTD程序设计天线。采用遗传算法对天线参数进行调谐。在不同侧面弯曲的胸部上测试弯曲模型。比较了回波损耗，定义了可用最大输入功率下的I-g平均比吸收率(SAR)。采用32曲面天线和22.5度弯曲模型与传统天线进行了比较。采用卡普顿和硅衬底的天线的最大输入功率分别为4.43 mW和4.46 mW。
