在这项工作中，设计了一种用于乳腺癌检测的柔性超宽带（UWB）天线。采用尺寸为32 mm × 32 mm × 0.75 mm的柔性PDMS介质（ε=2.7, tan δ= 0.02）印制双极化单极天线。在单极子的接地面和加载在单极子上的两个短桩之间增加了一条中和线，以提高天线之间的隔离。天线在自由空间覆盖的带宽从4.68 GHz到11.8 GHz，而当它安装在乳房组织上时，它的工作带宽在3.1 GHz到14 GHz之间。该天线具有较高的保真度，对乳房成像具有重要意义。
In this work, a flexible ultra-wideband (UWB) antenna is designed for breast cancer detection. Dual-polarized monopole antennas are printed on flexible PDMS dielectric (ε=2.7, tan δ= 0.02) with a dimension of 32 mm × 32 mm × 0.75 mm. A neutralization line connecting the ground planes of the monopoles and two stubs loaded at the monopole are added to improve the isolation between the antennas. The antenna covers a bandwidth from 4.68 GHz to 11.8 GHz in free space, whereas it operates between 3.1 GHz and 14 GHz when it is mounted on the breast tissue. High fidelity factor has been achieved by the proposed antenna, which is critical for breast imaging.
