A decoupling technique is able to reach high-level isolation ratio because it isolates two antennas in nearfield region. The isolation screen sandwiched between closely placed two monopole antennas proposed. The designedstructure with dimension of 220 mm by 140 mm simulated. The transmission coefficient between the monopoles withoutmetamaterial structure is about -26.49 dB. When the metamaterial Omega structure is inserted between the monopoleantenna, high isolation of -134 dB is achieved. Consequently, it provides high degree of isolation of 107.51 dB whichreduce the mutual coupling between the radiators. This isolation is valid from 1.0 GHz to 3 GHz.
