Abstract

An in-body implantable miniaturized slot dipole rectangular patch antenna operating in the Industrial, Scientific, and Medical (ISM) band (2.4-2.4835 GHz) for biomedical applications is presented in this paper. Primary reason behind choosing ISM band is its flexibility towards larger bandwidth with smaller size of antenna. The main specialty of this antenna is its tiny dimension & bendability which makes it practically implantable for in-body biomedical applications. Actual size of the antenna is (8.20×12.5×0.045) mm. For making it suitable for implementation, the antenna was immersed inside a human tissue model where proper electrical properties of the human tissue muscle model were maintained. All the parameter calculations and simulation results were suitable to support the Industrial, Scientific, and Medical (ISM) band in both bent and planar conditions. This antenna can be used for real time wireless monitoring of blood pressure, temperature, glucose level, and other in-body applications that functions in the ISM band. To make the designed antenna suitable for implantation, it is embedded in a silicon block which acts like a superstrate. Finally, the safety measurements were taken into account by stimulating the Specific Absorption Rate (SAR) distribution of the antenna to make it perfectly biocompatible.

生物医学用可植入微型槽偶极子矩形贴片天线的设计与性能测量

本文提出了一种用于生物医学应用的可植入体内的微型槽偶极子矩形贴片天线，工作在工业、科学和医疗(ISM)频段(2.4-2.4835 GHz)。选择ISM频段的主要原因是它可以灵活地以更小的天线尺寸实现更大的带宽。这种天线的主要特点是它的微小尺寸和可弯曲性，这使得它实际上可植入体内生物医学应用。天线的实际尺寸为(8.20×12.5×0.045) mm。为了使其适合实施，将天线浸入人体组织模型中，以保持人体组织肌肉模型的适当电学特性。所有参数的计算和仿真结果都适合于在弯曲和平面条件下支持工业、科学和医疗(ISM)波段。该天线可用于实时无线监测血压、温度、血糖水平和其他在ISM波段功能的体内应用。为了使所设计的天线适合植入，它被嵌入一个硅块中，起到上覆层的作用。最后，通过刺激天线的比吸收率(SAR)分布来考虑安全措施，使其具有完美的生物相容性。
