Compact Power Divider using Defected Ground Structure for Wireless Applications

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.
