Abstract
A simple tridimensional negative permeability metamaterial structure Split Ring Resonator (SRR) based on Low Temperature Co-fired Ceramic (LTCC) substrate is proposed to eliminate mutual coupling between array elements. Embedded SRRs can help in the reduction of mutual coupling by using their capability of suppressing surface waves propagation in a given frequency range. By placing the SRR array between two adjacent microstrip antennas, greater than 15 dB peak isolation is achieved for array elements spacing of 0.2λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> .
