Multi Polarization Antenna Structures for Efficient MIMO Systems Employing Software Radio Design Methodology

Author:
Narayanan Manoj   Amir Faizal   Smruti Santosh Palai  


Abstract(summary):

This paper presents the different States of Polarizations (SOPs) of the transmitting and receiving antennas that can be used for improving the efficiency of a MIMO system. The analysis is performed for a 3 in 3 out MIMO platform. A method for generating these SOPs is presented. Some simulation reports are provided for validating the concepts presented. One particular SOP which requires a 4.4 dB relative attenuation and a phase difference of 90 degrees between the linear vertical polarization (LVP) and linear horizontal polarization (LHP) feeds. The phase difference obtained has a deviation of approximately 1 degree with respect to the desired design specification of 90 degrees. This may be eliminated by employing alternate designs for the discrete phase shifter which gives higher resolution accuracy. The paper concludes with suggestions for future work.
