چکیده
Breast cancer is a disease that occurs most often in females. Early detection can increase the chance of a successful treatment. However, current breast-imaging systems such as breast ultrasound, X-Ray mammography, and magnetic resonance imaging (MRI) have their own disadvantages. Here a safe and inexpensive method which is called microwave imaging is presented. Ultra Wide Band systems are used for microwave imaging in order to increase the resolution. So, UWB antennas are so consequential. In this paper, a novel compact UWB antipodal Vivaldi antenna is presented which is used various slots to obtain required bandwidth with respect to Federal Communication Commissions (FCC) standard rules (۳.۱-۱۰.۶) GHz and includes low frequencies for better penetration depth and high frequencies for better resolution. The antenna is designed on RO ۴۰۰۳C, and its dimension are . Finally, with time-reversal multiple signal classification(TR-MUSIC) algorithm, the image of tumor in a breast is generated for ۲ scenarios with ۴ and ۶ number of antenna elements and it is shown that the tumor can be detected well with ۶ elements.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
