Mutual Coupling Reduction for Multiband Phased Array Antenna Using Metamaterial Surface for Millimeter Wave Communication

In this paper, we have designed multiband phased array antenna for millimeter wave (MMW) communication with high isolation by using metamatrials as mutual coupling techniques and ground structure defected, add slots and slits to get multiband. The designed antenna operates at 28, 36 and 43 GHz frequencies. To design the antenna we have used copper for the patch and ground, Rogers RT5880 as dielectric material. To enhance the isolation we have used SRR Metamaterial between the array elements to minimize the mutual coupling. The overall size of proposed eight element array antenna is 70 mm×7.89mm× 0.8mm. The simulation results show that the designed antenna exsibits good performance interms of bandwidth which is 5.64 GHz and isolation level of - 40dB with gain of 15.1 dBi and envelope correlation coefficient of 0.0001. The size and performance of the proposed antenna demonstrates that the designed antenna could be a good candidate for mobile handsets at the MMW.
