A MIMO Antenna Based on Cooperative Diversity for Improved Envelope Correlation Coefficient

Multiple-Input Multiple-Output systems are important for increasing the capacity in wireless channels. In MIMO system more than one antenna is used at both the transmitter and receiver sides. Compared to the usual wireless systems, the main advantages of the MIMO systems are thehigher system capacity, improved bit rates, more link reliability, and coverage area is wider. The emerging new services in wireless applications have created a great motivation to use the MIMO systems to complete the demands needed for these applications. The MIMO systems can be used with other new techniques to get the benefits by using a higher spectral efficiency. Co-operative diversity is a cooperative multiple antenna technique for increasing total network channel capacities for any given set of bandwidths In the proposed system modified 2x2 multi input multi output triangular microstrip patch antenna is designed and analyzed.
