Abstract

The design and experimental verification of a deeply implanted conformal printed antenna is presented. The hip implant acts as the ground plane for a coaxial-cable-fed trapezoidal radiator designed to transmit biological signals collected within the body by proper biosensors. The arrangement, consisting of a metallic (or equivalent) hip implant, bio-compatible gypsum-based dielectric, and conformal radiator, was tested when the hosting 3D-printed plastic bone was immersed in tissue-like liquid contained in a plastic bucket. The dimensions of the set-up are similar to a human leg. Matching and radiation characteristics are presented in the industrial, scientific, and medical (ISM) frequency band (2.4-2.5 GHz), showing the feasibility of the proposed arrangement.

摘要

提出了一种深度植入的共形印刷天线的设计和实验验证。髋关节植入物充当同轴电缆馈电的梯形辐射器的接地平面，该辐射器旨在通过适当的生物传感器传输体内收集的生物信号。当容纳 3D 打印塑料骨的宿主浸入装在塑料桶中的类似组织的液体中时，该由金属（或等效）髋关节植入物、生物相容的石膏基介电体和共形辐射器组成的装置进行了测试。该装置的尺寸与人类腿部相似。在工业、科学和医疗（ISM）频段（2.4-2.5 GHz）中展示了匹配和辐射特性，证明了所提出的布置的可行性。
