Implementation of Dielectric Resonator Integrated Microstrip Antenna for Improved Performance Characteristics

A dielectric resonator antenna is proposed in the given paper which results in increased gain and efficiency. Initially a simple rectangular microstrip antenna, 5.8GHz resonant was equipped with a 3.5dBi gain and a 60 per cent radiation output. A cylindrical structure is mounted to form a dielectric resonator on the simple microstrip antenna resulting in an improved 4.7dBi gain and an appreciable radiation output of 93 per cent. Finally, the idea of integrating dielectric resonator was introduced to further improve antenna gain. Thus two cylindrical holes are inserted over the microstrip antenna into the dielectric resonator, which achieves enhanced gain of 4.79dBi.
