This method is independent of the numerical method used in the analysis and it can include the effect of the antenna platform. The starting point can be the active element patterns or the spherical mode expansion from spherical near-field antenna measurements. Additionally, the spherical mode expansion is also used to find a matrix which allows the compensation of mutual coupling effects in receiving arrays. Through this theory, a simple relation between the compensation matrices of the transmitting and the receiving arrays is found. As a consequence, the scattering matrix of a circuit that allows the simultaneous compensation of mutual coupling effects for the transmission and the reception problem can be easily defined. Finally, it will be shown how the capabilities of the compensation in all directions depend strongly on the array element.}, keywords = {Active element pattern, antenna array, Antenna arrays, Antenna measurements, antenna radiation patterns, finite element analysis, Mutual coupling, mutual coupling compensation, spherical mode expansion, transmitting antennas, Vectors}, issn = {0018-926X}, doi = {10.1109/TAP.2014.2382691}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=6987253}, author = {Rubio, J and Izquierdo, J F and J C{\'o}rcoles} } @article {14_TAP_SANCHEZ-OLIVARES_PFC, title = {Novel Four Cross Slot Radiator With Tuning Vias for Circularly Polarized SIW Linear Array}, journal = {Antennas and Propagation, IEEE Transactions on}, volume = {62}, number = {4}, year = {2014}, month = {April}, pages = {2271-2275}, abstract = {A substrate integrated waveguide (SIW) linear array is presented with a new circularly polarized (CP) element.
