Abstract

In this research, an on-body capacitively loaded planer inverted-F antenna has been designed for biomedical applications, which is able to operate in MICS (Medical Implant Communication Service) band. The primary reason behind choosing MICS band (401MHz-406MHz) because of its availability, accepted propagation, safest frequency band for human body, characteristics etc. For making this antenna bio-medically suitable to use on human body tissue the antenna has mounted on the human body phantom model where all the properties of human body tissue have been maintained. The antenna is suitable for real time monitoring of different types body signals and also for communicating with other sensors related to on-body devices. To make this antenna bio-compatible and improve its performance an additional silicon layer has been used between the patch and human body phantom. As, this antenna is designed for biomedical applications it needs to be harmless to human body tissue, for which its SAR is calculated and found at a safety region. $\text{VSWR}< 2$, radiation pattern, bandwidth, return loss also observed through simulation and measurement by using CST microwave studio.

生物医学用电容负载平面倒f天线的设计与性能测量

在本研究中，设计了一种用于生物医学应用的体上电容负载平面倒f天线，该天线能够在MICS(医疗植入通信服务)频段工作。选择MICS频段(401MHz-406MHz)的主要原因是它的可用性、可接受的传播、对人体最安全的频段、特性等。为了使该天线在生物医学上适用于人体组织，该天线已安装在人体幻影模型上，其中保持了人体组织的所有特性。该天线适用于实时监测不同类型的身体信号，也适用于与其他与身体设备相关的传感器通信。为了使这种天线具有生物相容性并提高其性能，在贴片和人体幻影之间使用了额外的硅层。由于该天线是为生物医学应用而设计的，因此它需要对人体组织无害，因此计算并发现其SAR处于安全区域。$\text{VSWR}< 2$，辐射方向图、带宽、回波损耗也通过CST微波工作室模拟测量得到。
