UWB Sierpinski Fractal Antenna for Breast Tumour Detection Using SAR

Abstract

Abstract Breast tumour is the most common tumour in the world and one in eight women is likely to develop breast tumours. Survival rate is higher only when the tumour is detected at the early stages. The various methodologies currently available to detect breast tumour are ultrasound, MRI, X-ray mammography etc. But these methods are not cost effective and have other reliability issues. In this paper, tumour is detected by passing microwave signals into the homogeneous breast model by designing an Ultra-Wideband (UWB) Sierpinski fractal micro strip patch antenna (MSA) with reduced ground. SAR (Specific Absorption Rate) calculation helps to find the presence of tumour. The antenna characteristics are studied using CST studio suite 2017 software. Sierpinski fractals and reduced ground are used to achieve UWB and enhance bandwidth. The preferred antenna provides a bandwidth width of 9.71 GHz (2.79 - 12GHz).
