Low Profile Inset Feed Asymmetric Slotted MIMO Antenna for n261 Band mmWave Application

In the proposed research an inset feed MIMO antenna with asymmetric slots is designed for mm Wave n261 band (27.50 GHz – 28.35 GHz) on the Rogers RT 5880 substrate with size of 13.2 x 14.4 x 0.508 millimeter cube. The operating band w.r.t. 2:1 VSWR is 27.58 GHz – 28.37 GHz. The minimum gain in the design is 7.17 dBi, and at 28 GHz resonating peakgain is 7.65 dBi. The maximum value of envelope correlation coefficient is 0.00017, and the maximum channel capacity loss in the band is 0.33 bits/s/Hz. The minimum radiation efficiency and minimum total efficiency are 96.16% and 85.06% respectively in the band.
