MIMO ANTENNA PROPOSED OBJECTIVES To design a high capacity MIMO system at the frequency below 1 GHz and above 1 GHz. In this, the high capacity MIMO (Multiple-Input Multiple-Output) system at the frequency of 5.5 GHz was designed in HFSS (High-Frequency Structure Simulator) 13. The antenna design was the compact antenna based on the coplanar waveguide fed with hexagonal ring element antenna. Design a MIMO antenna with small size while obtaining a very high isolation coefficient. The MIMO antenna was designed by choosing the compact size. The size of the substrate was chosen as the (26x26) mm with the thickness of about 1.5 mm. The Antenna Array was printed on the FR4 Substrate having the Relative Permittivity of 4.4. The metallic SMA Connectors were also used in the model. The Coplanar waveguide (CPW) to the input port was taken as the 50 ohms. Overall Model
To compare the performance of proposed antenna with the existing antenna. RESULTS 1) Result of MIMO Antenna Array In this work, the results the improved to -61 dB Comparison of this work with the base work They are getting the Isolation as -10 dB, but in this improved work, the isolation is about -61 Db. In this work, the antenna size is compact as compared to the base paper. They have taken the substrate size as (25x40) mm, but in this case, the size of the substrate was taken in the more compact dimensions as (25x25) mm. 2) Radiation Pattern for rETotal Curve
