摘要：
An effective design on low sidelobe of Vivaldi phased array antenna in multi-antenna systems is presented in this article. The proposed antenna is printed on the Rogers RO4003 substrate. By choosing a proper selection of dimensions and structures of the hollow parts in the traditional Vivaldi antenna can get better isolation performance in multi-antenna systems. The antenna retains the advantages of ultra-wideband to work at the 4.8GHz to 10.4GHz and the relative bandwidth is 73.68% The maximum scan angel is 60 degrees and VSWR below 3. The quality of a multi-antenna system depends on effects of low frequency antennas to high frequency antennas, this antenna provides a way to solve the scattering problem among multi antennas.
