Ground slotted monopole antenna design for microwave breast cancer detection based on time reversal MUSIC

Abstract

In this manuscript, a reduced size, ground slotted monopole antenna, operating in the range of 3.1–10.6GHz is designed and implemented for breast cancer detection using time reversal MUSIC. A homemade breast mimicking phantom has been experimentally designed to facilitate the detection implementation. The simulated and measured results are in good agreement. The slots and blending edges of the ground, along with the feed step are some techniques applied to the designed antenna in order to achieve a broad bandwidth and reduce considerably the reflection coefficient. The resulting dielectric constant from the breast phantom is relatively close to the real normal breast tissues. After the design has been completed, some techniques of time reversal MUSIC were employed to mimic the breast cancer detection. The experimental results show that both temporal and spatial images of the cancer (tumor) are well represented here.
