Abstract

Biomedical implanted devices are typically used for interacting with organs and/or for investigating various physiological signals. Hence, enhanced performance devices for clinical uses have got the attention of researchers. In this study, a multi-band implanted microstrip antenna suitable for transmitting/receiving biomedical signals in the Industrial, Scientific and Medical (ISM) frequency bands is presented. The antenna is built on a bio-compatible substrate, as titanium dioxide (TiO2) with relative permittivity of 95. The ground plane is thought to be a bio-metallic implant located within a bone. The proposed antenna is compact in size, 14 × 18 × 1.6 mm3, and works in both 2.45 GHz and 5.8 GHz centered frequency bands. It is designed and optimized considering the actual biological tissues as bone, muscle, fat, and skin surroundings. The simulation results referring to a planar stratification prove that the multiband single microstrip antenna is working properly within the human body and it can be used for medical communication services.

大地平面和TiO2衬底多波段可植入微带天线

生物医学植入装置通常用于与器官相互作用和/或用于研究各种生理信号。因此，用于临床的高性能设备得到了研究人员的关注。本研究提出一种适用于工业、科学和医疗(ISM)频段发射/接收生物医学信号的多波段植入微带天线。该天线采用相对介电常数为95的二氧化钛(TiO2)作为生物相容性衬底。该接地面被认为是位于骨头内的生物金属植入物。该天线尺寸紧凑，为14 × 18 × 1.6 mm3，工作在2.45 GHz和5.8 GHz中心频段。它的设计和优化考虑到实际的生物组织，如骨骼，肌肉，脂肪和皮肤的环境。基于平面分层的仿真结果表明，该多波段单微带天线在人体内工作正常，可用于医疗通信服务。
