Abstract:
Every year a concerning number of women are affected by breast
cancer which is one of the deadliest and common types of cancers.
Breast cancer is curable at early stages. For detecting breast cancer,
there are several methods such as MRI, Mammography, Tomography,
Ultrasound, and biopsy are available in medical technology. Still, none
of them are as easy and efficient as a microwave imaging technique,
in this method, the antenna plays an important role. Therefore, this
paper focuses on developing an antenna at a low-frequency range for
microwave imaging techniques to detect cancerous tissue inside the
breast. For this, the antenna parameters, i.e., return loss, VSWR,
directivity, current density, and specific absorption rate were studied,
by setting the antenna over without tumor and with tumor breast as upside-down, to ensure the compatibility of the antenna for the technique
as well as for the patient’s body. A 5mm radius cancerous tumor was
created inside the breast with dielectric conductivity of 4 and relative
permittivity of 50. Cancerous cells were detected by reading the
antenna parameters’ comparison between the healthy breast and the
affected breast. The whole study was conducted by using CST
MICROWAVE STUDIO SUITE 2020.
