Abstract
This article proposed a novel miniaturized design of coplanar wave guide (CPW) fed ultra wide band (UWB) tapered slot Vivaldi antenna for microwave imaging applications. Broken line exponential tapered profile and different types of slots have been incorporated in order to obtain the better performance and miniaturized antenna. All the important performance parameters of the proposed antenna such as return loss, BW, gain, directivity, VSWR, axial ratio, front to back ratio, accepted power, radiated power, surface current, radiation efficiency have been analyzed and enhanced up to the acceptable level. Finally, from the simulated validation, it is noticed that the proposed antenna would be a potential candidate for microwave imaging applications.
