Abstract
In this article four element MIMO antenna design for Ultra wide band 3–7 GHZ is presented. The antenna is designed based on microstrip annular framework with rectangular slot. To enhance the separation between the elements an annular slot antenna with I shape patch on the ground plane is used as an element of multi-input-multi output antenna. Ant1 and Ant2 cover the lower band. Further the Ant3 and Ant4 covers the upper band. The proposed antenna is compressed in order to occupy a volume of 51 * 51 * 0.8 mm3. 19 dB isolation, which is measured between the antenna elements. The proposed antenna shows the good radiation characteristics with a high gain of 4.5 dBi. The performance characteristics of MIMO antenna is analyzed in terms of the scattering parameters, VSWR, antenna gain and radiation patterns. Analysis of these parameters indicates that the design is appropriate for ultra wide band applications.
