Wearable Antenna for Time-Domain Breast Tumor Detection

Abstract

There is a considerable year by year increase in the number of women suffering from breast cancer. Early diagnosis is important to ensure the survival of patients. 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.The antennas are all located in the cup of a bra, which is divided into four quadrants; each quadrant has two antennas for tumor detection. The parameters S11 and S21 for each antenna were measured in the frequency domain. The measured results of S11 and S21 indicate that the antennas worked well both with and without a breast phantom model at the assigned frequency. For antenna five, located in the third quadrant (the quadrant with the tumors), the signal response of the antenna on the breast phantom model had a higher amplitude than that without the breast phantom model. The results demonstrate that the antennas worked well for the detection of the tumors.

“…Breast cancer is the most common cancer in women worldwide [1]. According to data from the Ministry of Health of the Republic of Indonesia, there were a total of 68,858 new cases of breast cancer in Indonesia in 2020, indicating approximately 16.6% of the total new cancer cases of 396,914 cases across all regions in Indonesia [2].…”
