A new ultrawide-band (Uwb) microwave imaging system with minimized mutual coupling effects for breast tumor detection

Electromagnetic waves and antennas have a huge application area, and one of the challenging areas is remote sensing systems and detection systems using microwaves, today. Increasing demand on non-destructive sensing or detecting breast tumor keeps this subject hot in this field. There are various passive and active microwave techniques which have been proposed as an alternative to the most widely used X-ray mammography for early detection of breast cancer, such as microwave radiometry, hybrid microwave-induced acoustic imaging, microwave tomography and UWB microwave radar technique. Because of its excellent advantages, recent years have shown a dominant interest in a UWB microwave imaging technique, for a particular technique to detect and locate a breast tumor.This study will consist of an optimum antenna design with minimized mutual coupling effects, fabrication and testing for tumor detection. Realistic breast phantom models, as well as tumor-simulating objects, will be constructed for testing on. Images of the measured signals will be created as a function of position with fast and improved imaging algorithms. It?s aimed to get better resolution results than similar recent developed microwave imaging systems.
