Abstract :
Effect of curvature of antipodal structure on Vivaldi antennas is presented in this paper. The results indicate that inner curvature has a significant impact on the return loss S11. In addition, a new estimation of lower frequency limit is shown. Based on our design, an antipodal Vivaldi antenna has been fabricated and verified its properties through measurements.
