Aperture-Coupled Rectangular Dielectric Resonator Antenna for Multiband Applications

This paper introduces the simulation of a rectangular dielectric resonator (RDR) antenna for utilizing in Ku-band for tri-band. This antenna can be used for 5G cellular, satellite communication as broadcast satellite services (BSS) and fixed satellite services (FSS) applications. These terms, FSS and BSS, are used for video data transmission. The band 11.7–12.5 GHz segment is allocated to BSS and 12.5–12.7 GHz band is allocated to the FSS. The proposed RDR antenna is excited by aperture-coupled fed. RDR has cut a corner, set a metallic strip for controlling the multiband purpose and also control the resonance of the antenna. The antenna is reported peak gain 9.01 dBi and high radiation efficiency is above 90%. It is a high gain antenna so can be easily used in 5G applications.
