Abstract

A novel design of a flexible on-body matched microstripline-fed antenna for biomedical applications is proposed in this article. The core feature of the proposed antenna refers to its tiny dimension, bendability, low temperature co-fired ceramics (LTCC) substrate layer, impressive return loss, higher bandwidth that makes it appropriate for on-body matched wireless medical applications. The dimension of the antenna is 13.86 mm × 13.49 mm × 0.35 mm where substrate layer, LTCC layer has the thickness of 0.326 mm and on the other hand, the thickness of the radiating patch is 0.012 mm. The performance of the antenna was analyzed to operate in the Industrial, Scientific and Medical (ISM) band (2.4–2.5 GHz). Three layers of the human phantom model have been proposed as well as biocompatibility test, SAR calculations, flexibility, and several performance measurements have been utilized using CST Microwave Studio software in both curved and planar states by following different types of dielectric property matching with human tissue model. Finally, Specific Absorption Rate (SAR) is evaluated to check its feasibility and workability in wireless medical applications.

一种用于无线医疗应用的紧凑型微带线馈电体上匹配天线

提出了一种生物医学应用的柔性体上匹配微带状馈电天线的新设计。该天线的核心特点是其尺寸小，可弯曲，低温共烧陶瓷(LTCC)衬底层，可观的回波损耗，更高的带宽，使其适合身体匹配的无线医疗应用。天线尺寸为13.86 mm × 13.49 mm × 0.35 mm，其中基片层、LTCC层厚度为0.326 mm，辐射贴片厚度为0.012 mm。分析了该天线在工业、科学和医疗(ISM)频段(2.4-2.5 GHz)的工作性能。利用CST Microwave Studio软件，通过与人体组织模型进行不同类型的介电特性匹配，提出了人体幻影模型的三层结构，以及生物相容性测试、SAR计算、柔韧性和几种性能测量。最后，评估了比吸收率(SAR)，以验证其在无线医疗应用中的可行性和可操作性。
