Abstract :
A rectangular patch antenna array for MIMO communications was simulated on a magnetic permeability enhanced metamaterial. The performance of this antenna array was studied relative to a similar array constructed on a regular substrate. The analysis was performed with respect to performance metrics such as degree of mutual coupling for different element spacing, achievable channel capacity, bandwidth and efficiency. The array built on the metamaterial substrate showed significant size reduction, less mutual coupling and significant channel capacity improvement compared to similar arrays on conventional substrates.
