In this paper, a novel multiband implantable planar inverted-F antenna (PIFA) antenna based on Gosper curve fractal geometry is designed for biomedical telemetry applications. The antenna has covered four dedicated frequency bands; medical implant communication system band (MICS 402–405 MHz), industrial, scientific, and medical bands (ISM 902–928 MHz and 2.4–2.5 GHz), and wireless medical telemetry services (WMTS 1395–1400 and 1429–1432 MHz). The proposed antenna is designed on Rogers RO 3010 substrate of thickness 25 mil and volume equal to 153.67 mm3. The reflection coefficient and the radiation pattern are measured inside muscle-mimicking liquid tissue phantom. The antenna has achieved the impedance bandwidth of 126, 406, 168, and 175 MHz at MICS (403 MHz), ISM (915 MHz), WMTS (1400 MHz), and ISM (2.45 GHz) with maximum gain value −33.6, −21.04, −15.48, and −10.25 dBi, respectively. The data link range between the implantable antenna and off body antenna has been performed with −16 dBm input power. Additionally, the obtained specific absorption rate with the input of 25 μW power has also been obtained within the safety limit and hence ensures the reliability of the proposed antenna.

在本文中，设计了一种基于 Gosper 曲线分形几何的新型多波段可植入平面倒 F 天线 (PIFA)，用于生物医学遥测应用。天线已覆盖四个专用频段；医疗植入物通信系统频段（MICS 402–405 MHz）、工业、科学和医疗频段（ISM 902 – 928 MHz 和 2.4–2.5 GHz）以​​及无线医疗遥测服务（WMTS 1395–1400 和 1429–1432 MHz）。建议的天线设计在 Rogers RO 3010 基板上，厚度为 25 mil，体积等于 153.67 mm 3. 反射系数和辐射模式是在肌肉模拟液体组织模型内测量的。该天线在MICS（403 MHz）、ISM（915 MHz）、WMTS（1400 MHz）和ISM（2.45 GHz）下实现了126、406、168和175 MHz的阻抗带宽，最大增益值为-33.6，-分别为 21.04、-15.48 和 -10.25 dBi。植入式天线和离体天线之间的数据链路范围已在 -16 dBm 输入功率下执行。此外，在输入 25 μW 功率的情况下，所获得的比吸收率也在安全范围内获得，从而确保了所提出天线的可靠性。
