The paper presents a compact monopole antenna with an integrated circularly polarized band for wireless communication. The proposed monopole antenna having a defected ground structure which uses two L-shaped slots of equal size and an unsymmetrical slot of inverted E-shaped. These slots in the ground patch are used for achieving dual band notching. The radiating patch is embedded with a staircase rectangular shape radiator( i.e. two equal square slots are detached from the lower corners). This radiating patch is used to generate the two current modes in 90 degree phase deviation and approximately equal magnitude by which circularly polarized radiation is generated. The measured results show that the proposed dual polarized monopole antenna offers a very high gain with 10 db return loss and multi notched bands, covering all the (3.1-3.5) GHz WiMAX, (5.07-6.05) GHz WLAN, (6.75-8.95) GHz X bands, (3.5-5.07)GHz C-band for satellite application.
