Patch Antennas in Medical Imaging- A Critical Analysis for Cancer Diagnosis

Cancer poses a worldwide health issue, with millions of new cases diagnosed annually, presenting a substantial challenge to public health. This literature review explores the dynamic landscape of patch antenna-based non-destructive testing (NDT) in the realm of cancerous tissues. It navigates through the existing body of research, highlighting the urgent need for comprehensive exploration within this interdisciplinary domain. It underscores the necessity for refined antenna designs, innovative signal processing techniques, and rigorous validation studies tailored to the distinct challenges of cancer detection in biological tissues. The review aims to compile and synthesize the various inventive approaches and methods proposed in recent research endeavors, shedding light on the potential of patch antennas to revolutionize the early identification and characterization of cancerous tissues. Through an extensive analysis of the current state of research, this review not only emphasizes the critical areas for improvement but also lays the foundation for future inquiries, ultimately propelling the field towards transforming cancer diagnostics with non-invasive, cost-effective, and highly efficient NDT solutions.
