摘要：
A novel wideband filtering power divider based on coupled-lines and short-circuited stubs is proposed in this paper. By using multisection lambda/4 coupled-lines with two short-circuited stubs placed in shunt with the input port of the power divider, the presented circuit can successfully realize wideband property and high frequency selectivity. In addition, two resistors are properly selected according to the even-/odd-mode analysis for improving the isolation performance. For demonstration, two typical ideal simulations with 15-dB bandwidth of 80% and 20-dB bandwidth of 56% operating at 2 GHz are implemented, respectively. The simulated results show excellent agreement with theoretically predicated results.
