Metallic Object Detection Inside Human Stomach With Antipodal Vivaldi Antenna Utilizing Microwave Imaging Technique

An Ultra-Wideband (UWB) Antipodal Vivaldi Antenna (AVA) is introduced here for microwave imaging applications. The AVA accomplishes high transmission capacity from 1.2–14 GHz with a maximum gain of 13 dBi at 10 GHz. The antenna is utilized for the identification of a metal object located inside a human stomach cross-section modelled in the simulator. A suitable imaging algorithm is devised to identify the material inside the stomach. The algorithm can locate the exact coordinates of the metallic objects along with their actual dimensions used in the simulations. Further, the resolution of the image has been improved.
