Abstract

A flexible implantable PIFA (Planar Inverted F Antenna) antenna for biomedical applications is proposed in this study. The main notability of this design refers to its subtle dimension, flexibility and subordinate thickness that makes it perfectly suitable for implementing inside human or animal tissues. The antenna is aimed to operate in the Industrial, Scientific and Medical (ISM) band (2.4–2.4835 GHz). The thickness of this antenna is only .735 mm, which implies that this antenna is reliable to perform under bent conditions. The antenna offers a compact design with a dimension of 9.48 mm × 7.8 mm × .735 mm (54.348 mm3). Copper and Rogers R03010 are chosen as the patch material and substrate material accordingly. The antenna is encapsulated inside biocompatible material Rogers R03010 for safety concern in skin or muscle tissues. Several types of calculations and performance measurement of this antenna have been done by using CST Microwave studio in both planar and bent conditions by maintaining all the electrical properties of human skin tissue. Finally, Specific Absorption Rate (SAR) and thermal loss are evaluated to comply with the antenna safety issues.

ISM频段WBAN微型植入式PIFA天线性能分析

本研究提出一种柔性植入式PIFA(平面倒F天线)天线，用于生物医学应用。这种设计的主要特点是其微妙的尺寸，灵活性和从属厚度，使其非常适合在人体或动物组织内实施。该天线的目标是在工业、科学和医疗(ISM)频段(2.4-2.4835 GHz)工作。该天线的厚度仅为0.735 mm，这意味着该天线在弯曲条件下工作可靠。天线设计紧凑，尺寸为9.48 mm × 7.8 mm × .735 mm (54.348 mm3)。贴片材料和衬底材料选用铜和罗杰斯R03010。天线被封装在罗杰斯R03010生物相容性材料中，以保证皮肤或肌肉组织的安全。利用CST微波工作室在平面和弯曲条件下，通过保持人体皮肤组织的所有电学特性，对该天线进行了几种类型的计算和性能测量。最后，评估了比吸收率(SAR)和热损耗，以符合天线安全问题。
