Multiband Vivaldi Antenna for X and Ku band Applications

A Multiband vivaldi antenna is designed to operate in the X and Ku bands and simulational results are presented in this paper. Along with the ultrawide band, this particular vivaldi antenna is working in the range between 7 to 20 GHz at different resonent frequencies. Gain of more than 9dB and bandwidth enhancement of 0.92% can be achieved using this model. All the antenna parameters including design considerations and field distributions are presented in this paper.
