Abstract

Abstract Medical telemetry applications rely heavily on biomedical implanted antennas. These biomedical implanted devices can enhance and monitor patients’ daily life circumstances. A low-profile, downsized size implanted antenna operating at 915 MHz in the industrial, scientific, and medical (ISM) band is suggested in this research. The antenna is a simple slotted patch supplied by a 50-impedance coaxial probe. The radiator is made up of two slotted parasitic patches with one square-shaped outer radiator are manufactured on a Roger Droid RT5880 substrate with a standard height of 0.254 mm (εr = 2.2, tanδ = 0.0009). The entire dimension of the given antenna is 11 × 11 × 0.2514 mm with an electrical size of 0.049λg × 0.049λg × 0.0011λg. The antenna spans a bandwidth of 0.82–1.05 GHz when working inside muscle tissues (25.13 percent). The antenna’s calculations and experimental findings are quite similar. The computed specific absorption rate (SAR) values inside muscle of above 1 g mass tissue are 7.25 W/kg, according to the data. The stated SAR values are lower than the limit set by the Federal Communications Commission (FCC). As a result, the proposed small antenna is a strong contender for biological implantable applications.

用于宽带生物医学遥测应用的新型微型化植入式天线

摘要医学遥测应用在很大程度上依赖于生物医学植入天线。这些生物医学植入设备可以增强和监测患者的日常生活情况。本研究提出了一种在工业、科学和医疗（ISM）波段工作在915MHz的低剖面、小型植入天线。天线是一个简单的开槽贴片，由50阻抗的同轴探头提供。散热器由两个开槽寄生贴片组成，其中一个方形外散热器在标准高度为0.254 mm（εr=2.2，tanδ=0.0009）的Roger Droid RT5880基板上制造。给定天线的整个尺寸为11×11×0.2514 mm，电气尺寸为0.049λg×0.049λg×0.0011λg。当在肌肉组织内工作（25.13%）。天线的计算和实验结果非常相似。根据数据，超过1g质量组织的肌肉内计算的比吸收率（SAR）值为7.25W/kg。所述SAR值低于联邦通信委员会（FCC）设定的限值。因此，所提出的小型天线是生物植入式应用的有力竞争者。

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.
