A Dual Band Four Ports WILKINSON Power Divider Design

In the present paper, a dual band four-way Wilkinson power divider (WPD) using a genetic algorithm (GA) optimization is designed and simulated using ADS Momentum simulator. The proposed power divider is developed to support dual bands of WLAN applications. The present power divider is formed by many transmission lines sections. The transmission lines are printed on FR4 (Flame Resistant 4) substrate of dielectric constant
$\varepsilon_{\mathrm{r}}$
of3.4 with loss tangent of 0.0023. The proposed circuit exhibits good characteristics at WLAN frequencies (2.45GHz & 5.8 GHZ) in terms of return loss and isolation.
