MIMO antenna design with low ECC for mmWave

To accomplish promises of 5G technology like blazing speeds, massive throughput, capability and ultra-low latency, antennas should be designed having compact designs, high gain, high efficiency, very low return loss, and very low ECC. To achieve all these requirements, researches are required to switch to array and MIMO antennas with low loss tangent substrates such as Rogers Duroid, etc. The proposed design is a combination of an array and MIMO so that all the needed requirements can be fulfilled in 5G in the best possible manner. A 2x8 array-MIMO antenna is designed on Rogers Duroid 5880 substrate with substrate’s dimension of 23.83 x 53.52 x 0.79 mm³. Each patch with inset-feed is uniquely designed with radius, ’r’ = 1.44 mm to achieve sharp peak at 28.0 GHz resonant frequency. The gain of 10.67 dBi and radiation efficiency of 88.2% is achieved at 28.0 GHz in 27.572 - 28.648 GHz frequency band with respect to 2:1 VSWR band.
