Rotman lens beamforming network to achieve, the phased array antenna can enhance the performance of Ad Hoc network mobile node. In this paper, the design of C-band Rotman lens is introduced. The design equations of microstrip Rotman lens are deduced. The selection of the array beam number in the scan angle range is demonstrated according to the system technical requirements. The selection principle of lens design parameters is discussed. Tool, this paper designs a C-band Rotman lens and completes simulation verification using Planer EM, a planar circuit simulation tool. According to the design of the lens, a prototype prototype of the lens was made and measured. The simulation is consistent with the measured phase, and the simulation is in good agreement with the measured array factor.
