摘要

本文提出了一种用于诊断胚胎期皮肤肉瘤的小型天线。天线面积为 30.54 × 15.27 mm2，谐振频率为 1429 MHz，反射系数为 -17.64 dB。天线结构由 1.6 毫米 FR-4 基板上蚀刻的 35 μm 铜片组成。诊断依据的是共振频率偏移和天线放置在恶性组织上时的 SAR（比吸收率）变化。模拟时考虑了三层人体模型（皮肤、脂肪、肌肉）和半球形肿瘤模型。对天线性能的模拟显示，对于 100 μm 的肿瘤，谐振频率和 SAR 分别降低了 2 MHz 和 1.09 mW/Kg。除了肉瘤检测外，该天线的 3.6 dBi 增益还能在复杂环境中实现 124.47 米的生物医学通信链路。

Skin sarcoma stage detection using antenna resonant scale

In this paper, a small antenna is proposed to diagnose skin sarcoma at an embryonic stage. The antenna has an area of 30.54 × 15.27 mm2 and resonates at 1429 MHz with a reflection coefficient of −17.64 dB. The structure consists of a 35 μm copper sheet etched on a 1.6 mm FR-4 substrate. The diagnosis is based on the resonance frequency shift, and the SAR (Specific Absorption Rate) variation when the antenna is positioned on malignant tissue. For the simulations, a three-layer body phantom (skin, fat, muscle), and a half-sphere tumor phantom were considered. Simulations of the antenna performances showed that for a tumor of 100 μm, the resonant frequency, and the SAR decrease by 2 MHz, and 1.09 mW/Kg, respectively. In addition to sarcoma detection, the antenna’s 3.6 dBi gain allows for 124.47 m biomedical communication links in a complex environment.
