In this paper, a wideband rotman lens with corresponding antenna array is presented. The antenna array consists of 14 Vivaldi antennas with same size. The rotman lens has 8 beam ports and 14antenna ports. It can achieve <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">± 30∘</tex> scanning range during 6-18GHz. To improve design efficiency, co-simulation technology is used. Through results of the co-simulation, the performance of rotman lens and corresponding antenna array can be evaluated easily.
