Rajesh English N https://doi.org/10.55524/ijircst.2023.11.3.11 A 8x8 multiple input multiple output antenna is developed for the applications of MM wave. this proposed model has 8 ports on the single structure of antenna system. The proposed design gives a triple bands k-band (14.6 at-22dB), ku-band (19.6 at -28dB) and ka-band (27.6 at -27dB) which this ka-band wii be act as mm wave band for the applications of MM wave. The proposed antenna having the dimensions of 64mm x 32mm x 1.6 mm having thickness 1.6mm and the Fr4 substrate has been used for designing. The proposed antenna is designed, measured and tested English MIMO Antenna, MM Wave, Multi-Band antennas, 5G, Mobile Communication https://ijircst.org/abstract.php?article_id=1140
