  In this article, a microstrip tri-band Wilkinson power divider, using the equivalent three section transmission line instead of common quarter-wavelength transmission line with help of PSO algorithm, design and simulated. Optimized choices for electrical lengths of equivalent three section transmission line, characteristic impedances of lines and finally design of three resistors for high isolation between output ports will be obtained. The results of the researches in this article show that the proposed Wilkinson power divider, besides high isolation between output ports, will be a tri-band Wilkinson power divider to be used in communication wireless systems such as GSM 850 , GSM 900 , GPS, GSM1800 ، GSM 1900, UMTS, WLAN and WiMAX. Next, the designed Wilkinson power divider is going to be simulated by CST-MW 2013 software. The result of simulation show that the proposed structure, analysis and design method are suitable.
