A coupled stripline power divider based on a two-layer dielectric substrate bonded by a prepreg is proposed in this paper. The power divider consists of two-stage coupled striplines and a 50 ohm resistor connected to the coupled stripline, which enables the power divider to have good isolation and matching over a wideband of $8 \sim 16$ GHz. The microstrip line input and output are realized through the transition structure of the microstrip line to stripline. The designed power divider has been fabricated and measured. The test results are in good agreement with the simulation results. In the $8 \sim 16$ GHz frequency band, the return loss is greater than 10dB, the insertion loss is less than 4.19dB, and the isolation is greater than 18dB.
