In this paper, a miniaturized Vivaldi antenna for Cto X-bands is proposed and fabricated. An H-Shaped Resonator (HSR) and transverse slot structures are employed in this design, which improve the gain through the entire band, especially at the high frequency band. These simulated results show that the modified Vivaldi antenna has a maximum gain increment of 4 dBi and peak gain of 9.9 dBi. Furthermore, the modified Vivaldi antenna has narrower half-power beam width (HPBW), higher frontto-back ratio (FBR) and better radiation characteristics. The measured results are in good agreement with the simulated ones.
