In this paper, an Archimedean spiral antenna-based biosensor has been proposed for the early detection of breast tumor. By monitoring the variation of S 11 over 1–3.5 GHz frequency range, the proposed scheme can identify the tumor location, as well as distinguish the types of tumor (benign or malignant) based on shapes and dielectric properties contrast. To validate the concept, full wave simulation using CST microwave suite are performed along with VNA based experimental measurements on breast phantoms and tumors, prepared by easily available materials like glass, petroleum jelly, mixture of water and wheat flour. The demonstrated device is able to detect the tumor of less than 1 mm in radius and positioned anywhere in 5 × 5 × 5 cm of breast fat. The proposed method is easy to use, low cost, safe, comfortable, non-invasive and non- ionizing in nature.

螺旋天线在早期对乳腺肿瘤的无创检测和鉴别

本文提出了一种基于阿基米德螺旋天线的生物传感器，用于乳腺肿瘤的早期检测。通过在1–3.5 GHz频率范围内监视S 11的变化，提出的方案可以识别肿瘤的位置，并根据形状和介电特性对比来区分肿瘤的类型（良性或恶性）。为了验证这一概念，使用CST微波套件进行了全波模拟，并基于VNA对乳房幻影和肿瘤进行了实验测量，这些实验测量是由容易获得的材料（例如玻璃，凡士林，水和小麦粉的混合物）制备的。演示过的设备能够检测到半径小于1毫米的肿瘤，并将其放置在5×5×5 cm乳脂中的任何位置。所提出的方法易于使用，成本低廉，安全，舒适，
