Abstract

Implantation depth of Implantable Medical Devices (IMDs) is an important factor of communication quality between implantable antennas in IMDs and external devices. Therefore, it is required to study the effect of implantation depth on implantable antenna performance. In this article, dependence of resonant frequency and scattering parameters of a two-antenna system where one miniaturized meander-line antenna is placed within human muscle tissue layer operating at 2.45 GHz ISM (industrial, scientific and medical) band and a rectangular patch antenna placed outside human body, are tested. Here 15 values of implantation depth ranging over 5–35 mm inside muscle layer are taken and for each case resonant frequency and scattering parameters (S 11 and S 21) of the system are recorded. Statistical analysis has been performed to observe how these performance parameters are dependent on depth of implantation which may be varied at the time of surgery.

随植入深度变化的肌肉植入天线性能分析

植入式医疗设备（IMD）的植入深度是影响植入式医疗设备中的植入式天线与外部设备之间通信质量的一个重要因素。因此，需要研究植入深度对植入式天线性能的影响。本文测试了双天线系统共振频率和散射参数的相关性，其中一个微型蜿蜒线天线放置在人体肌肉组织层内，工作在 2.45 GHz ISM（工业、科学和医疗）频段，另一个矩形贴片天线放置在人体外。在此，对肌肉层内 5-35 毫米范围内的 15 个植入深度值进行了测试，并记录了每种情况下系统的谐振频率和散射参数（S 11 和 S 21）。我们进行了统计分析，以观察这些性能参数如何依赖于植入深度，而植入深度在手术时可能会发生变化。

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.
