Wideband four-way microstrip power divider for WLAN application

Abstract

The Wilkinson power divider is a well-known device in the RF and microwave community used for splitting power. It is composed of simple transmission line and isolating resistor, and takes advantages of the properties of quarter-wavelength transmission line section to perform ideal power divider characteristic. Two-way power divider or also known as Wilkinson power divider is as power divider with one input port and two output ports. Basically, Wilkinson power divider has very high isolation between its two output ports. It is also lossless if all the output port mismatched. In this project, wideband Four-way microstrip power divider for WLAN application is proposed. Four-way microstrip power divider was designed by combine or interconnecting the two-way Wilkinson power divider. Through this project, it is focus on the performances of its S-parameter which is reflection coefficient, insertion loss, isolation and also bandwidth. Simulated result of reflection coefficient, S11 shows a good result, 2.443 GHz with -28.641 dB and covers a wide bandwidth with 1.84 GHz which suitable for the WLAN application.
