Slotted Rectangular Dielectric Resonator Antenna for the Application of Satellite Communication

Rectangular Dielectric Resonator Antenna (RDRA) is utilized for the wireless communications system because of its miniaturized size and low profile. This paper presents a design and simulation of slotted RDRA for satellite communication. The major aim of the work is to attain a high gain and radiation efficiency. Hence, the parasitic patch is introduced in this work to achieve this requirement. In this work, the RDRA is designed with a compact size of 10 × 10 × 3 mm, which operates at 17.04 GHz for satellite communication applications. The design is evaluated on the substrate ROGERS RT DUROID 5880, and the antenna comprises Alumina (Al₂O₃) ceramic material. The slotted design provides better impedance bandwidth and gain. The entire work is simulated in Ansys HFSS software. The performance measures like gain, return loss, radiation pattern, VSWR and directivity are simulated and fabricated. The proposed design provides circularly polarized characteristics at 3 dB and better radiation efficiency of 100%. At last, the fabricated design prototype is analyzed and provides better performance. The simulated and fabricated outcomes proved that the proposed slotted RDRA is efficiently exploited for satellite communication.
