A Broadband Stripline Wilkinson 2-way Power Divider

This paper mainly introduces the design method of the broadband stripline power divider. Based on the Wilkinson power divider, a broadband one-to-two power divider is designed. First, the parameters of the power divider are roughly simulated by ADS, and then the HFSS is used. Carrying out accurate simulation, combining the two simulation software, a Wilkinson stripline power divider with a working bandwidth of 1.2 GHz-3.4 GHz is designed, The overall size of the power divider is 21.5 mm $\times$ 31.44mm $\times$ 2 mm. The simulation results show that: in the working bandwidth, the return loss is greater than 20 dB. The transmission loss is less than 3.3 dB, and the isolation of the output port is greater than 17 dB.
