SQUARE SPLIT RING MIMO ANTENNA FOR WIMAX /WLAN APPLICATIONS WITH REDUCED ECC

A high gain 2-element MIMO antenna operating in 5.1 – 5.75 GHz band is proposed in this paper. A Square Split Ring (SSR) antenna element is designed, simulated and fabricated on a conventional FR-4 substrate. Performance of an array of SSR antenna is investigated in terms of envelop correlation coefficient (ECC). For Square Split Ring Antenna element, Gain of 5.8 dBi is obtained along with the 810 MHz impedance bandwidth. Then ECC is calculated using scattering parameters and its value comes out to be 0.0001 with inter-element spacing of 0.25mm i.e. d=Normally value of ECC should range between 0.5 to 0.7 for the interelement spacing of We have reduced ECC to very low value inspite of very small inter-element spacing. Circular Polarization of SSR-MIMO Antenna makes this suitable for the use in various mobile applications.
