Abstract

Use of different types of defected ground structures (DCS) has been reported in this paper to design compact power dividers in microstrip medium. Unit cell´s (of DGS) equivalent circuit has been used to evaluate the performance of power divider. Based on this approach, compact two-way equal power dividers have been designed in GSM (900 MHz) band. Results show a size reduction of 35% and 32% for the power dividers using T shaped DGS and split ring DGS over the conventional power divider.
