Abstract

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. Grooves can change the current distribution on the antenna surface, so as to influence the gain of the antenna element, and can make the pattern more evenly. The test and simulation results show that the pattern of the modified Vivaldi antenna is more smooth than the traditional Vivaldi antenna, and the antenna gain is improved in the whole operating range.
