This paper highlights a3-Band 4-Element Multiple Input Multiple Output (MIMO) Antenna in Small Size with better Isolation using Half-Mode SIW. Half-mode substrate integrated waveguide (HMSIW) concept is used in designing this antenna to reduce the losses, to increase power handling capacity and to minimize the antenna size. In order to operate this antenna in triple frequencies an F-shaped patch is loaded outside the radiating aperture of the HMSIW. A coaxial feed is used to feed the cavity, while a proximity coupling is used to feed the radiating patch through the radiating aperture of the HMSIW. For the formation of a 2x2 array, the antenna elements are assembled by rotation and orthogonal arrangement. According to simulated data, the antenna resonates at 3.85GHz,5.44GHz, and 9.4GHz, with gains of 9.9dB,7.1dB, and 19.3dB, respectively. The isolation at all bands is in the range of 25-55dB. The envelope correlation coefficient is below 0.02. The size of MIMO antenna is 82x82x1.57mm3. The diversity gain achieved with the proposed antenna is 10 dB. Ansys HFSS software is used for the simulation purpose. This antennawould be bestsolution for 5G NR applications, Radar and Satellite communication applications.
