Abstract

A dual-band bio-implantable compact antenna with a meander-line structure is presented. The proposed meander-line antenna resonates at the industrial, scientific, and medical (2.4 GHz) and wireless medical telemetry (1.4 GHz) bands. The meander-line structure is selected as a radiating patch given its versatile and effective design. With a dimension of only $10 mm \times 10 mm \times 0.635 mm$ , the designed antenna is compact. Considering a skin phantom, the proposed antenna was designed, optimized, and simulated. The Rogers RT/duroid 6010 substrate material with high dielectric constant was used to fabricate the meander-line dual-band implantable antenna, which was validated experimentally. The superstrate was made of the same material. Experiments were conducted on skin-mimicking gel. The designed meander-line antenna has a high peak gain of −21 dBi at 2.4 GHz, and its maximum specific absorption rate is compliant with IEEE safety standards.

用于生物遥测应用的微型化弯曲线双波段植入式天线

本文介绍了一种具有蜿蜒线结构的双频生物植入式紧凑型天线。所提出的蜿蜒线天线可在工业、科学和医疗（2.4 GHz）和无线医疗遥测（1.4 GHz）频段产生谐振。选择蜿蜒线结构作为辐射贴片，是因为它的设计既通用又有效。设计的天线尺寸仅为 10 mm × 10 mm × 0.635 mm，结构紧凑。考虑到皮肤模型，对所提出的天线进行了设计、优化和仿真。采用具有高介电常数的罗杰斯 RT/duroid 6010 衬底材料制作了蜿蜒线双频植入式天线，并进行了实验验证。基板由相同材料制成。实验在皮肤模拟凝胶上进行。所设计的蜿蜒线天线在 2.4 GHz 频率下具有 -21 dBi 的峰值增益，其最大比吸收率符合 IEEE 安全标准。
