Reduction of Isolation in MIMO Antenna Using Rupee Shaped Structure
Description
A novel concise Rupee shaped micro strip patch antenna with CPW (Co-planar Waveguide Feed) is designed, which is used for Multiple Input Multiple Output (MIMO) systems. The described two element MIMO system reproduces at a dual band of 4.696 GHz and 7.723 GHz with an enhanced impedance bandwidth of 33.33% and a minimized mutual coupling of –35.3 dB. These results are better when compared to a normal E shaped, H shaped, U shaped patch antennas plotted with identical size and thickness, obtained without using any further decoupling methods. A 2×2 MIMO system employing the Rupee shaped patch antennas is analyzed using computational electromagnetic ray tracing software for an indoor environment. The described antenna is a good choice for MIMO systems operating for several Ultra Wide Band (UWB) applications.
