The mutual coupling between elements of a multifrequencydipole antenna array is experimentally investigated by S-parameter measurements and planarnear-field scanning of the radiated field. A multifrequency array with six dipoles is analyzed.In order to reduce the coupling between dipoles, a planar metasurface is placed atop the arrayacting as superstrate. The mutual coupling of the antenna elements in the absence and presenceof the superstrate is presented comparatively. Between 3 and 20 dB mutual coupling reductionis achieved when the superstrate is used. By scanning the field radiated by the antennas andfar-field measurements of the radiation pattern, it is observed that the superstrate confines theradiated power, increases the boresight radiation, and reduces the endfire radiation
