Wearable Antenna for Time-Domain Breast Tumor Detection

Abstract

There has been a considerable year-on-year increase in the number of women suffering from breast cancer. Early diagnosis is important for the early survival of victims. This study presents the development of a novel wearable and flexible Multiple Input Multiple Output (MIMO) 2 × 4 antenna design, which operates at a frequency of 5.5–7 GHz for time-domain breast tumor detection. All antennas are located at the cup of the bra, which is divided into four quadrants; each quadrant has two antennas for tumor detection. The parameters S11 and S21 of each antenna are measured in the frequency domain. The measured results of S11 and S21 indicate that the antennas work well with/without the breast phantom model at the assigned frequency. For antenna five, located in the third quadrant (quadrant with tumors), the signal response of the antenna with the breast phantom model has a higher amplitude than that without the breast phantom model. These results demonstrate that the antennas work well for tumor detection.
