BREAST CANCER DETECTION BY T-SHAPED SLOTTED RECTANGULAR MICROSTRIP PATCH ANTENNA

Abstract
This Paper shows the great achievement in the breast cancer detection by microwave imaging ,in this paper firstly the T-Shaped Slotted RMPA is designed for ISM band Application at 2.45 GHz and resonated at particular frequency by iterations on the simulation software and very low losses is shown on particular exact frequency is 32.2dB ,after that The Breast Phantom model with cancer tissues and RMPA with its center is designed and simulated Current density and SAR of the model is calculated which is 1288A/m2 and 3.10*105 respectively and after that Breast Phantom model is designed 50mm away from the RMPA and results shows that current density is reduced about 11times its value is 107.4A/m2

The signal scattering by an object depends on various factors, including the environment, signal strength, and the material properties of the object .For a given signal source and the environment, the scattered signal depends on the electrical properties of the object, especially dielectric and conductivity. This principal is utilized to detect the tumor in the breast using microwave signals. Reflected signals also reflected from various part of the breast which is undesirable in microwave imaging because we want that signal should reflect only from tumors so we have to place the antenna very closest to the breast. The breast tumors have very distinct electrical properties (higher dielectric permittivity and higher conductivity), which allows them to detect by analyzing the scattered signals Microwave breast imaging (MBI) uses low power and longer wavelength signals (compared to X-ray mammography) to obtain information about breast tissues, and promises a safer and more accurate modality for regular breast
