“…Voltage Standing Wave Ratio or VSWR parameter represents the antenna matching-capability with the system. An antenna VSWR value needs to be less than 2 and VSWR value 1 is considered as ideal VSWR value [15]. From Figure 6, it is clear that the antenna is well matched with the system, as for all of the statuses such as with tumor and without tumor of the breast the antenna's VSWR values are less than…”

“…Specific Absorption Rate, in brief SAR, is the essential parameter to consider as it is an exhibitor of patient safety. It mainly indicates the amount of antenna's radiated electromagnetic energy that is absorbed by the near side body tissue [15]. The antenna's SAR values for the breast with diverse positioned tumors are calculated at their center frequencies due to patient safety purposes.…”

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.
