Abstract
Exploiting advantage of Dielectric Resonator Antennas (DRA), in this dissemination a novel superman-diamond inspired shaped DRA has been proposed for X-band applications. Furthermore, possibilities of Multiple Input Multiple Output (MIMO) DRA explored using proposed novel shaped DRA and a two-element MIMO DRA has also been proposed for X-band applications. Proposed DRA made up of anisotropic composite ceramic material with dielectric constant 10 has been placed on the substrate with dielectric constant 3.55 and thickness 20 mil. Proposed DRA and MIMO DRA have demonstrated 11.7% and 9.5% impedance bandwidths, respectively. Other performance characteristics of MIMO DRA such as mutual coupling, isolation between ports, ECC, TARC have also been examined. To validate the performance of proposed DRA, simulated performances have been compared between two electromagnetic simulator solvers
