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.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
