Description
Summary:A Simulation of a small sized antipodal Vivaldi antenna for ultra-wideband (UWB) applications is presented in this paper. By using commercial electromagnetic simulation software CST Microwave, some parameters like return loss (S 11 ), Voltage Standing Wave Ratio (VSWR), radiation pattern has been performed to test the validity of simulation and verify eligibility of the antenna for UWB systems. The antenna design with dimensions of 58×60 mm achieves satisfactory impedance matching and radiation across the frequency band from 2.14 to 11.33 GHz with more than 136% fractional bandwidth.
