One of the most prevalent and dangerous diseases among women worldwide is breast cancer. The early identification of this disease is therefore crucial. However, typical methods for diagnosing breast cancer have some drawbacks. In order to overcome these disadvantages, microwave imaging methods have been developed. This study presents the design and modification of a rectangular micro strip patch antenna on an FR-4 substrate operating at 2.45 GHz in the ISM band for breast cancer detection. Both the proposed antenna and a five-layer breast phantom with and without a 5 mm-radius tumor were designed using CST software. To detect the presence of a tumor, distance dependent simulations were performed between the antenna and the breast phantom. The simulation outcomes revealed that the return loss, electric field, magnetic field, and surface current all change when a tumor is present in the breast phantom. Moreover, our results indicated that the antenna located 20 mm from the breast phantom can identify the tumor more efficiently compared to the antenna located at 40 mm. We also observed that the VSWR of the antenna is lower than 2, which is an acceptable limit for radiation. Due to its tumor detection capability and acceptable SAR values, our proposed antenna can be used as a sensor in biomedical applications.
