Microwave Imaging for Breast Cancer Detection: A Planar Array Antenna Design

The leading cause of cancer-related deaths in women is breast cancer. The likelihood of survival can be significantly increased by early detection of breast cancer. Breast cancer detection using microwave imaging has shown promising results because it is non-invasive and inexpensive. In order to create an image, microwave imaging works by passing microwave signals through the breast tissue and measuring the signal. Since cancerous tissues have different electrical properties than healthy tissues, they interact with microwaves differently. Since microwave imaging uses non-ionizing radiation, numerous studies have demonstrated its potential for breast cancer detection. To increase the technique's precision and dependability, more study is required. Designing an antenna for microwave breast cancer imaging is the goal of this work. . The frequency range of 20-30 GHz offers a good resolution and penetrative power required for imaging. A planar array design has been chosen to provide high directivity for the antenna. The detection is simulated using EMPro© for various positions and sizes of the tumor. The proposed system is able to successfully detect tumors as small as 1.25 mm.
