Abstract

Wireless implantable body area network (Wi BAN) technologies have improved the health monitoring system for the medical diagnostic of instance heart attack, BP(blood pressure) and breast cancer. The aim of present work, to model a UWB (Ultra-Wideband) implantable microstrip patch antenna resonating at 4.8GHz applicable for Wi BAN applications. The designed antenna is modelled on liquid crystal polymer (LCP) substrate by using high frequency structural simulator (HFSS) software. In this work, rectangular patch with 2 L slots have been proposed to achieve the 4.8GHz operating frequency for Wi BAN applications. The antenna parameters such as RC (reflection coefficient), operating BW (Bandwidth), VSWR (Voltage standing wave ratio) and radiation pattern have been analysed to understand the performance of the antenna. The designed antenna is operating from 4.21-5.67 GHz with the bandwidth of 1.46GHz and resonating at 4.8GHz with the reflection coefficient of −43dB. Gain of designed antenna is 7.77dBi at operating frequency.

一种用于无线植入式体域网络(Wi - BAN)的超宽带贴片天线的设计与分析

无线植入式身体区域网络(Wi - BAN)技术改进了健康监测系统，用于心脏病、血压和乳腺癌的医疗诊断。本研究的目的是模拟一种适用于Wi - BAN应用的4.8GHz谐振的UWB(超宽带)可植入微带贴片天线。利用高频结构模拟器(HFSS)软件在液晶聚合物(LCP)衬底上对所设计的天线进行了建模。在这项工作中，我们提出了具有2 L插槽的矩形贴片，以实现Wi - BAN应用的4.8GHz工作频率。对天线的反射系数、工作带宽、驻波电压比和辐射方向图等参数进行了分析，以了解天线的性能。设计的天线工作频率为4.21 ~ 5.67 GHz，带宽为1.46GHz，谐振频率为4.8GHz，反射系数为- 43dB。设计天线在工作频率下的增益为7.77dBi。
