Microstrip patch antennas with mutual coupling are proposed for WiMAX applications. To reduce mutual coupling between patch antennas using different methods like Split Ring Resonators (SRR), Slotted Meander Line Resonators (SMLR), Wave Guided MeTa Materials (WG-MTM) and Planar-Electromagnetic Band Gap (P-EBG) structures are designed for WiMAX applications. In all four methods, antennas are engraved on 15x10 mm2 FR4 substrate. The antenna is designed by applying FR4 substrate with thickness 3mm, permittivity 4.6. The proposed antennas are modeled using ADS software.
