<jats:p>This do In this paper, based on the Wilkinson power divider, a modified Wilkinson power divider using a microstrip in isolation is discussed. It can reduces the size of the circuit board area. What’s more, the isolation bandwidth can be extend by the Wilkinson power divider using a microstrip in isolation. Firstly, this paper illustrates the principles of the traditional Wilkinson power divider. By introducing the concept of isolation network, the real and imaginary part of the traditional Wilkinson power divider are derived. And then, the principle diagram the Wilkinson power divider with RLC isolation network are shown, we also give the expression of the real part and imaginary part of the isolation network. Lastly, we introduce the modified Wilkinson power divider using a microstrip in isolation, and give the expressions of real part and imaginary part of the isolation network, and the above three kinds of real part and imaginary part of Wilkinson power divider are simulated. Through simulation, we found the power divider using a microstrip in isolation has better physical performance.</jats:p>
