A design of modified Vivaldi antenna [PDF]
Proceedings of the 2016 5th International Conference on Advanced Materials and Computer Science, 2016 Conventional Vivaldi antenna has the advantages of ultra wideband, but its backward radiation is too large and the the gain of the main radiation direct is low (1). On the basis of the original Vivaldi antenna, this paper designed a Vivaldi antenna element with a groove, its working frequency is from 400 MHz to 900 MHz.
