Abstract

The desire for wearable ultra-wideband antennas has grown up rapidly in recent years. This paper presents a wearable ultra-wideband (UWB) antenna fed by a coplanar waveguide (CPW) on paper substrate and analysis of its performance for early detection of brain stroke. A very thin sheet of paper is considered as substrate in order to make the antenna flexible, wearable, low-cost and environment friendly. The antenna shows reflection co-efficient of -10dB or less at frequencies between 1.91 GHz to 34.45 GHz. It covers the 2.36-2.4 GHz MBAN (Medical Body Area Network) band, 2.4-2.5 GHz ISM (Industrial, Scientific and Medical) band, 3.1-10.6 GHz UWB and internet of things (IoT) frequency bands and 5G communication bands. Specific Absorption Rate (SAR) is calculated placing the antenna to a 7-layer human head model only 5 mm apart in order to check the compatibility of the antenna for wearable applications. Improvement in SAR is also shown comparing with other antennas. Improvement of SAR and other simulation results of the proposed antenna make it suitable for wearable applications.

用于脑卒中早期检测的cpw馈电超宽带柔性圆盘单极天线设计

近年来，人们对可穿戴超宽带天线的需求迅速增长。本文提出了一种基于纸基共面波导馈电的可穿戴超宽带天线，并对其用于脑中风早期检测的性能进行了分析。为了使天线具有灵活性、可穿戴性、低成本和环保性，我们考虑用一张非常薄的纸作为衬底。在1.91 GHz至34.45 GHz的频率范围内，天线的反射系数为-10dB或更低。它涵盖了2.36-2.4 GHz MBAN(医疗体域网络)频段、2.4-2.5 GHz ISM(工业、科学和医疗)频段、3.1-10.6 GHz UWB和物联网(IoT)频段以及5G通信频段。计算特定吸收率(SAR)，将天线放置在7层人体头部模型上，相距仅5毫米，以检查天线对可穿戴应用的兼容性。与其他天线相比，其SAR性能也有所提高。该天线的SAR等仿真结果的改进使其适合于可穿戴应用。
