Design of uwb monopole antenna for the analysis of breast tumor

Abstract

In this day and age, breast tumour is emerging as the prime newlineconcern for women, which leads to increased death rate. For early detection newlineof breast tumor, although X-ray mammography is commonly practiced for newlinecancer screening, few drawbacks such as false detection and alarm rate, newlinediscomfort and pain due to exposure to ionizing radiation, low resolution newlineimage. To obtain high resolution image, women are being compelled to breast newlinecompression and increased mental and physical stress. newlineMicrowave imaging is a promising alternative, which provides newlinehigh resolution image and good depth of penetration. Breast tissue is newlinecomprised of fibro-glandular, fatty tissues and skin. The basic axiom of newlinemicrowave imaging is the dielectric dissimilitude between normal and newlinemalignant tissues. The pernicious tissue has higher dielectric constant than newlinenormal tissue. newline newline
