Abstract

In biomedical applications, compact implantable medical devices (IMDs) must effectively handle space constraints and a variety of frequency requirements, makes the need of multiband and miniature antennas. This article proposes a novel flexible biodegradable antenna with dual band suitable for deep tissue implants and IIoMT. The designed antenna is fabricated on Mangosteen Bio Polymer with an overall dimension of 13 × 10 × 1.07 mm³. The antenna exhibits wider impedance bandwidth of 565 MHz and 2.12 GHz at ISM band (2.4–2.48 GHz) and Sub6 5G band (1–6 GHz) respectively. Achieved peak gain of the antenna are −25.91 dB and −39.93 dB. Extensive simulations were performed for safety analysis, telemetry and realization is validated by experimenting in minced pork. The antenna can withstand maximum power limit of 2.3mW enabling protective radiation of SAR. Finally the biotelemetry feature was analyzed using USRP and it shows the antenna is capable to transmit /receive signals with 2Mbps up to 15 m. With wider bandwidth, lower SAR, higher gain and biodegradable nature the antenna is well suited for bio implantable devices.

一种用于生物遥测的紧凑、灵活和可生物降解的双宽带植入式天线

在生物医学应用中，紧凑型植入式医疗设备（imd）必须有效处理空间限制和各种频率要求，因此需要多频段和微型天线。本文提出了一种适用于深层组织植入和iomt的双波段柔性可生物降解天线。设计的天线由山竹生物聚合物材料制成，整体尺寸为13 × 10 × 1.07 mm3。该天线在ISM频段（2.4-2.48 GHz）和Sub6 5G频段（1-6 GHz）的阻抗带宽分别为565 MHz和2.12 GHz。天线的峰值增益分别为- 25.91 dB和- 39.93 dB。对安全性分析进行了广泛的模拟，遥测和实现通过肉糜实验进行了验证。该天线可以承受最大功率限制为2.3mW，从而实现SAR的保护辐射。最后，使用USRP分析了生物遥测特性，表明该天线能够以2Mbps的速度发送/接收信号，最远可达15 m。该天线具有更宽的带宽、更低的SAR、更高的增益和可生物降解的特性，非常适合生物植入式设备。
