Design and Analysis of Microstrip Patch Antenna for Breast Tumor Detection

Globally, breast cancer is the most prevalent cancer form to be diagnosed in women. Medical methods such as ultrasound, MRI, and X-ray all have several drawbacks. Two distinct types of three-dimensional (3D) breast phantoms have been built using CST microwave studio in combination with an ISM-frequency band microstrip patch antenna to identify the presence of a malignant tumor. The purpose of this work is to use SAR analysis and variations in S11 characteristics to identify the malignant tumor in a breast phantom. Other parameters including reflection characteristics, Directivity, and SAR have been analyzed to accomplish this goal. The tumor may be easily identified in this procedure because the reflection coefficient changes when a tumor is present in the breast phantom. This method is superior to others for detecting malignant tumors because living tissues are not ionized by the microwave, keeping them safe.
