Abstract: Antenna high gain, wide bandwidth, reconfigurability and compact design has been long requirements in the field of mobile communications and aeronautics. This paper experimentally investigates superstrate layer of arrays placed above the dielectric resonator antenna (DRA), which can largely enhance the gain of antenna. Experimental and simulated results of gain with and without superstrate have been investigated. The superstrate arrays placed on DRA has improved the antenna gain, i.e., 8.7 dBi to 12.27 dBi. The effect of high permittivity material has been studied for gain and bandwidth improvement. Barium strontium titanate (BaSrTio³) mixed with silicon oil was used in DRA. Superstrate array have resulted into gain improvement to the extent of 28%. The design frequency was kept at 6.59 Ghz and verified theoretically using MATLAB. Height of substrate and dielectric constant affected the gain and bandwidth. Theoretical, simulated and experimental results have been compared and found in good agreement.
