Abstract

The most important technique for exposing early-stage breast cancer is terahertz imaging. It aids in lowering the number of breast cancer-related fatalities and enhancing the quality of life. An essential component of developing the THz imaging system for high-quality photos is choosing the right sensor. In this article, a wideband antenna for microwave imaging of breast tissue with an operating frequency of 30 GHz (107 GHz to 137 GHz) is constructed and analyzed. An aperture-coupled antenna with an optimized ground aperture is proposed and analyzed, which made it possible to obtain better and consistent impedance matching in the wideband spectrum. The variation of backscattered signal energy in body tissue is assessed with healthy breast tissue and in the presence of malignant cells. A significant difference in energy scattering is observed for both situations. The suggested antenna's linear and stable time domain characteristics make it an appropriate component for THz imaging technology.

摘要

用于检测早期乳腺癌的最重要技术是太赫兹成像。它有助于降低与乳腺癌相关的死亡人数，并提高生活质量。开发用于高质量成像的太赫兹成像系统的一个关键要素是选择合适的传感器。在本文中，构建并分析了一种用于乳腺组织微波成像的宽带天线，其工作频率为30吉赫兹（107吉赫兹至137吉赫兹）。提出并分析了一种具有优化接地孔径的孔径耦合天线，这使得在宽带频谱中能够获得更好且一致的阻抗匹配。利用健康乳腺组织以及存在恶性细胞的情况评估了人体组织中背向散射信号能量的变化。在这两种情况下都观察到了能量散射的显著差异。所建议天线的线性和稳定时域特性使其成为太赫兹成像技术的合适组件。
