Microwave hyperthermia is an effective adjuvant treatment for breast cancer. Tumor of 1-2 cm size is generally treated by hyperthermia. Local hyperthermia enhances the effects of anticancer drugs when used with chemotherapy and or radiotherapy. In breast hyperthermia, uniform heating of tumor also damages skin and healthy tissues of the breast. The available applicators for microwave hyperthermia are costly and bulky. This article presents a simple, cost-effective, and compact dual-band slotted rectangular monopole antenna (SRMA). The proposed SRMA design is suitable for breast hyperthermia treatment (HT). It offers dual frequencies (f1 = 2.45 GHz and f2 =5.5 GHz) for HT. The dual-band frequencies are widely suitable for deep-seated and superficial breast tumors treatment. CST-MW tool is used for antenna and tri-layer breast model design. Electromagnetic (EM) and thermal solvers are used for coupled simulation. The performance of the SRMA is evaluated for a hyperthermia treatment duration of 40 min. Evaluated SAR is within the specified limit of IEEE C95.1 standard. The thermal simulation results states that temperature distribution inside the tissue is in safe limits. The proposed applicator is suitable for breast hyperthermia. It helps to reduce hotspots. Standard FR4 substrate is used for fabricating this compact antenna. It fulfils the requirements for oncological application in breast hyperthermia, as per the IEEE C95.1 standard.
