Design of Wilkinson Power Divider for Mobile and WLAN Applications

Abstract

– In microwave and radio frequency (RF) applications, the power divider is a well-known threeport device that is very essential. It can be used extensively in balanced power amplifiers, radar systems,and phase shifters. It is well-known that the power divider bearing Wilkinson's name is the most wellknown and respected of all power dividers.This divider uses a single frequency band and has two lines witha length of L= λ/4 (quarter wave). It operates on a single frequency f=c/λ.The primary function of these microwave devices is to establish a power distribution from an input signalto a predetermined number of output signals. This is a very important duty for these devices.This power divider that has been presented has a design that includes three output ports. Optimisation withthe help of the HFSS simulator will make it possible to have a power divider for applications related toWLAN (the band will cover WLAN at a frequency of 2.4 GHz).The standard Wilkinson power divider (WPD) may have a straightforward design, but despite its ease ofconstruction, it offers satisfactory performance despite its restricted bandwidth (isolation).
