Abstract :This research focus on two aims, the first one is design a multi-band rectangular Microstrip Patch Antenna with spacious bandwidth by using Complementary Split Ring Resonator insert ignore into journalissuearticles values(CSRR); beside the Rectangular Ruler Patches insert ignore into journalissuearticles values(RRPs); and the second is improvement the performance and bandwidth for WiMAX and GPS applications by using Circular Head Dumbbell Structure CHDS beside Circular Ring Patches CRPs. A patch antenna is designed and simulated for 4.66 and 5.61 GHz. Two substrates of FR-4 lossy are utilized with 4.3 dielectric constant, 1.4mm and 0.2mm thickness. The shape used for conventional patch antenna is rectangular with a central feed source. For metamaterial antenna CSRR and CHDS are used. RRPs and CRPs that are used with metamaterial behave like Reactive Impedance surface RIS. The conventional antenna operates at a frequency band of 4.66 GHz and 5.61 GHz, while the designed antenna with CSRR generates four wide band resonant modes at 4.36, 4.7, 5.6 and 5.9 GHz, therefore considered as a multiuse antenna. CHDS appears fixed behavior with all RIS used to confirm its importance in WiMAX and GPS applications. Computer Simulation Technology CST EM simulator is used for this survey
