Design and Analysis of Multi Slotted Micro-Strip Patch Antenna Operating in ISM Band for Breast Cancer Detection

Breast cancer is the primary cause of death among women globally and existing screening techniques are both invasive and costly. In this research work, a rectangular microstrip patch antenna is simulated to identify the existence of a tumor by observing the impacts in the ISM band (2.4 GHz-2.5 GHz) of microwave signals. A simplified model of normal and contaminated breast tissue, antenna substrate Flame Retardant 4 (FR-4), copper ground and patch components are used in our study. To evaluate the effectiveness of the device, a human breast phantom made of layers of glandular and epidermal tissue was developed. A voltage standing wave ratio (VSWR) of 1.112869 and an S-parameter value of -25.44603 dB was obtained. A comparative study of the antenna performance is accomplished with and without the presence of a tumor. The assessed simulated performance implies that it can be an enhanced, precise, and reliable screening technique for breast cancer detection.
