Abstract
This paper presents the design and analysis of cylindrical shaped dielectric resonator MIMO antenna. The designed antenna was excited using coplanar waveguide feeding with rectangular L-shaped slots placed on the ground plane. The antenna was characterized using ANSYS Electromagnetic Desktop 17.0 (HFSS). Compared to the conventional microstrip antennas, the proposed dielectric resonator antenna has several advantages such as smaller dimension, high gain, and good radiation characteristics which are more suitable for millimeter wave range applications. The proposed antenna has better radiation characteristics with a peak gain of 9.08 dB, efficiency toward radiation is 97%, return loss bandwidth is 2.3 GHz, and it also offers front-to-back ratio of 16.3 dB at resonating frequency 60 GHz.
