Abstract
Supergain property and diversity performance in closely spaced antenna array are demonstrated in this work. It is commonly believed that the array spacing has to be greater than 0.5lambda to avoid mutual coupling and correlation between the elements. By applying a multiport impedance matching network, electrically oversampled antenna array is separated into decoupled and orthogonal radiation modes, which lead to the supergain and diversity enhancement.
