Abstract

Radar based microwave imaging (MI) has been widely studied for breast cancer detection in recent times. Sensing dielectric property differences of tissues over a wide frequency band has been made possible by ultra-wideband (UWB) techniques. In this paper, a flexible, compact monopole antenna on a 100 μm Kapton polyimide is designed, using a high frequency structure simulator (HFSS), to be in contact with biological breast tissues over the 2-5GHz frequency range. The antenna parameters are optimized to obtain a good impedance match over the required frequency range. The designed antenna size is 18mm × 18mm. Further, a flexible conformal 4×4 ultra-wideband antenna array, in a format similar to that of a bra, was developed for a radar-based breast cancer detection system.

摘要

近年来，基于雷达的微波成像（MI）在乳腺癌检测方面得到了广泛研究。超宽带（UWB）技术使得在宽频带上感知组织的介电特性差异成为可能。本文使用高频结构模拟器（HFSS），设计了一种位于100μm聚酰亚胺 Kapton 上的柔性紧凑型单极天线，使其在2 - 5GHz频率范围内与生物乳腺组织接触。优化天线参数以在所需频率范围内获得良好的阻抗匹配。所设计的天线尺寸为18mm×18mm。此外，还为基于雷达的乳腺癌检测系统开发了一种类似胸罩形式的柔性共形4×4超宽带天线阵列。
