摘要

Due to the broadband requirements in the field of communication, Ultra-Wide Band antennas have become popular nowadays. In this study, an antipodal Vivaldi antenna with UWB and compact design was investigated for X band applications. The antenna features have been developed using Defective Ground Surfaces (DGS) and dielectric lenses. The Vivaldi antenna was designed in the CST Microwave Studio Environment to work with RTDroid5880 material (dielectric constant=4.88, height= 0.76mm) in the 8-12 GHz band range. In this study, the Vivaldi antenna structure was chosen; because it is cost-effective and easily producible in production over 1 GHz. In addition, the performance enhancement of the antenna in the study is given in the bandwidth of 8-12 GHz in terms of simulated return loss and propagation gain characteristics.
