Decoupling and Decorrelation of Two Closely Spaced Monopoles for Optimum MIMO Capacity

In this work it is shown by simulations and measurements that a decoupling network can be used resulting in low correlation between two closely spaced antennas and increases the total received power of the antenna system. Two possible circuits for an antenna separation of 0.21 lambda are proposed operating at the center frequency of 2.45 GHz.
