Design & Simulation of Microstrip Antenna for Cancer Diagnosis

Breast cancer affects many women, and early detection aids in fast and effective treatment. Mammography, which is currently the most popular method of breast screening, has some limitations, and microwave imaging offers an attractive alternative. In this paper we have design cancer diagnosis model which consist of a microstrip antenna, breast model and tumor in HFSS 11. This model shows that tumor present in breast can be detected by observing the change in the distribution of volume current density of the breast with tumor and without tumor. Our model shows that the maximum current density of the breast in the presence of the tumor is (275.61A/m) and maximum volume current density of the breast in the absence of the tumor is (109.5 A/m). And the minimum current density of the breast in the presence of the tumor is (1.16A/m) and minimum volume current density of the breast in the absence of the tumor is (1.08 A/m). This particular technique is competitively easier and safer than mammography and tomography in which we use high intensity X-rays for the detection of breast cancer.
