Mutual coupling has always been a drawback for array antennas with different configurations. Engineers are obliged to cope with negative effects of mutual coupling in designing procedure. The most important cause of the mutual coupling is surface wave propagation as it transfers the wave in undesirable directions. A method to reduce this effect is the suppression of surface waves using metamaterial structures. A known type of metamaterial used for this purpose is complementary of split ring resonator (CSRR). In this work, a structure consisting of CSRRs with wires is used to alleviate the effect of mutual coupling. The results are verified by calculating effective permeability and permittivity of the structure showing the Mu‐negative property. The calculation is also performed by Kramers‐Kronig relations. A 17 dB reduction in mutual coupling is achieved over a bandwidth range of 170 MHz.
