Abstract

In this paper, we present the design of a compactsized dual-band implantable PIFA antenna for biomedical applications. The antenna’s overall size is 8× 8× 0.635 mm3 and radiates in the ISM band with the frequencies 915 MHz and 2.442 GHz. A layer of superstrate is placed over the patch to prevent direct contact between the radiating patch and body tissue. The antenna is simulated in a four-layer human arm model (skin, fat, muscle and bone). The antenna demonstrates a gain of -3.57dB and -2.80dB with a -10dB bandwidth of 135 MHz and 338 MHz for the two resonances respectively. The specific absorption rate is 0.01 W/kg for 1 g of fabric, which satisfies the safety criterion of the FCC standard. The simulated results are compared to existing antennas, which show that this antenna is an excellent candidate for implantable applications due to its remarkable performances in terms of miniaturization, power gain, bandwidth and SAR.

基于多层人体模型的915和2450 MHz ISM遥测小型化多槽双波段PIFA天线设计

在本文中，我们提出了一个紧凑的双频植入式PIFA天线用于生物医学应用的设计。天线的整体尺寸为8× 8× 0.635 mm3，辐射在ISM频段，频率为915 MHz和2.442 GHz。在贴片上放置一层上层材料，以防止辐射贴片与身体组织直接接触。天线在四层人体手臂模型(皮肤、脂肪、肌肉和骨骼)中进行模拟。该天线的增益为-3.57dB和-2.80dB，两种谐振频率的-10dB带宽分别为135 MHz和338 MHz。1g织物的比吸收率为0.01 W/kg，符合FCC标准的安全标准。仿真结果表明，该天线在小型化、功率增益、带宽和SAR等方面具有优异的性能，是可植入天线的理想选择。
