摘要

本文的主要目的是从市售的无机聚合物陶瓷、聚酰胺和有机衬底材料中选择合适的生物相容性衬底用于体内植入式天线。在衬底相对介电常数变化范围为2.5< εr < 30的条件下，我们首先考虑了2.45 GHz的体内天线，然后对其进行了优化。在将天线与体模集成后，我们监测天线反射系数、最大允许辐射功率以及组织中的比吸收率(SAR)，从而制定适合无线植入式医疗设备(WIMDs)的衬底材料选择策略。

Selection of Suitable Inorganic/Organic Substrate for In-Body Antenna Implants: Impact on Antenna Characteristics in Deep Tissue Environment

This paper is primarily aimed at choosing the suitable biocompatible substrate for in-body implantable antennas from a pool of commercially available inorganic polymer ceramics, polymides and organic substrate material. We first consider an in-body antenna at 2.45 GHz, and then optimize it without body phantom, for range of substrate relative permittivity variation 2.5< εr < 30. After integrating the antenna with body phantom, we monitor the antenna reflection coefficient, maximum permissible radiated power, as well as specific absorption rate (SAR) in the tissue, in order to formulate a strategy for suitable substrate material selection in Wireless Implantable Medical Devices (WIMDs)
