摘要

本文提出了一种新型的微型可植入PIFA (Planar inverned - f Antenna)，工作在工业、科学和医疗(ISM)频段(2.4-2.4835 GHz)，用于无线体域网络应用。该可植入天线的实际尺寸为8mm × 6mm × 1mm (48mm3)，无插槽接地面，降低了设计复杂性。该天线的微小尺寸使其非常适合无线体域网络(WBAN)应用。铜被用作贴片材料，Rogers RO3210被用作天线的衬底材料。为了避免与人体直接接触，天线还采用了罗杰斯RO3035生物相容性材料进行封装。利用CST Microwave Studio对三层人体组织模型在平面和弯曲条件下，天线的工作频率、S11参数、驻波比、指向性、总效率等不同性能参数进行了分析。最后，对天线的比吸收率(SAR)进行了评估，以满足天线对人体的安全考虑。

Design and Performance Analysis of a Miniaturized Implantable PIFA for Wireless Body Area Network Applications

A novel and miniaturized implantable PIFA (Planar Inverted-F Antenna) operates at the industrial, scientific and medical (ISM) band (2.4-2.4835 GHz) is proposed in this paper for wireless body area network applications. The actual dimension of the proposed implantable antenna is 8 mm × 6 mm × 1 mm (48 mm3) with a slot-less ground plane which reduces the design complexity. The tiny dimension of the proposed antenna makes it perfectly suitable for wireless body area network (WBAN) applications. Copper is used as the patch material and Rogers RO3210 is used as the substrate material of the proposed antenna. Biocompatible material Rogers RO3035 is also used to encapsulate the antenna to avoid direct contact with the human body. Different performance parameters of the antenna such as operating frequency, S11 parameter, Voltage Standing Wave Ratio (VSWR), directivity, total efficiency have been analyzed both in planar and bent conditions on the three-layer human tissue model by using CST Microwave Studio. Finally, Specific Absorption Rate (SAR) is evaluated to satisfy the antenna safety concern on the human body.
