Abstract

In this study, a low-profile, co-planar waveguide (CPW) fed, wideband, and dual-ring slot antenna design for biomedical applications is proposed. The proposed antenna has a total area of 10 mm × 10 mm and a height of 0.4 mm, and is designed by using a thin and biocompatible FR4 epoxy (εr = 4.4) substrate to accomplish human body isolation and great flexibility obtained by implantation. This wideband antenna covers a large bandwidth of industrial scientific and medical (ISM) frequency band, including 902.8 MHz to 928 MHz, 1.395 GHz to 1.4 GHz, 1.427 GHz to 1.432 GHz, 2.4 GHz to 2.485 GHz, and above. The simulation results of return loss, voltage standing wave ratio (VSWR), impedance matching, gain, and radiation pattern of the proposed antenna are obtained through High Frequency Structure Simulator (HFSS) 14 software.

生物医学应用的低轮廓宽带双环槽天线

在这项研究中，提出了一种低轮廓，共面波导(CPW)馈电，宽带，双环槽天线设计用于生物医学应用。该天线的总面积为10 mm × 10 mm，高度为0.4 mm，采用薄而具有生物相容性的FR4环氧树脂(εr = 4.4)衬底设计，实现了人体隔离，并且通过植入获得了很大的柔韧性。该宽带天线覆盖工业科学和医疗(ISM)频段的大带宽，包括902.8 MHz ~ 928 MHz、1.395 GHz ~ 1.4 GHz、1.427 GHz ~ 1.432 GHz、2.4 GHz ~ 2.485 GHz及以上频段。利用高频结构模拟器(HFSS) 14软件对天线的回波损耗、驻波比、阻抗匹配、增益和辐射方向图进行了仿真。
