In this paper, compact broadband microstrip patch antenna with circular slot has beendesigned for various wireless applications suitable in the ranges ofDCS1800/PCS1900/UMTS2100. The designed antenna has been printed on dielectricsubstrate glass epoxy. The Zeland IE3D software is used for the simulation. The return lossbandwidth is of 89.07% covering the frequency range of 1.02 to 2.65 GHz. The experimentalresults are in good agreement with the simulated results and have maximum radiationefficiency of 97%. Keywords: Broadband antenna, line feed, circular slot, radiation pattern.
